Messages lost from imap folders
by Nikolaos Milas 19 Sep '15

19 Sep '15

Hello, We have one user who is complaining that he has lost mails from 3 imap folders, administered through squirrelmail. The folders suddenly appeared unregistered, and once manually registered they were empty. Has anyone observed something like this? We are running two servers (as VMs) with Dovecot v2.2.18, synced (two-way) using dsync. The configurations follow. Can you please help me understand what may have gone wrong? Can I try to find actions regarding these folders in the logs? What should I search for? Could this be an issue involving dsync? How can I trace back dsync activity in detail? Server configs follow (I have only altered the real domain name and the login greeting.) Thanks in advance, Nick ----------------------------------------------------------------------------- SERVER 1 ----------------------------------------------------------------------------- protocols = imap pop3 login_greeting = Hello World! mail_location = maildir:~/Maildir/ mail_gid = 500 mail_uid = 500 auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes auth_debug = no mail_debug = no disable_plaintext_auth = no mail_plugins = quota notify replication protocol imap { imap_client_workarounds = "delay-newmail" mail_plugins = quota imap_quota notify replication } protocol pop3 { mail_max_userip_connections = 3 mail_plugins = quota notify replication pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master info_log_path = log_path = mail_plugins = quota notify replication postmaster_address = sysadmin(a)example.com sendmail_path = /usr/lib/sendmail } userdb { args = /etc/dovecot/dovecot-usrdb-ldap.conf driver = ldap } passdb { args = /etc/dovecot/dovecot-passdb-ldap.conf driver = ldap } dsync_remote_cmd = ssh -l root vmail1.example.com doveadm dsync-server -u%u replication_dsync_parameters = -d -N -l 30 -U plugin { mail_replica = remote:vmail@vmail1.example.com } plugin { quota = maildir:User quota quota_rule = *:storage=5G quota_rule2 = Trash:storage=+3%% quota_warning = storage=75%% quota-warning 75 %u quota_warning2 = storage=90%% quota-warning 90 %u } service quota-warning { executable = script /opt/mail1.sh user = vmail unix_listener quota-warning { user = vmail } } service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service replicator { unix_listener replicator-doveadm { mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } user = root } service imap-login { service_count = 1 vsz_limit = 64 M } service pop3-login { service_count = 1 vsz_limit = 64 M } service replicator { process_min_avail = 1 } service imap { executable = imap postlogin } service pop3 { executable = pop3 postlogin } service postlogin { executable = script-login -d rawlog unix_listener postlogin { } } ssl_ca = </etc/pki/tls/certs/chain-1552.pem ssl_cert = </etc/pki/tls/certs/cert-1552.pem ssl_key = </etc/pki/tls/private/key-1552.pem ssl_protocols = !SSLv2 !SSLv3 syslog_facility = local1 ----------------------------------------------------------------------------- SERVER 2 ----------------------------------------------------------------------------- protocols = imap pop3 login_greeting = Hello World! mail_location = maildir:~/Maildir/ mail_gid = 5000 mail_uid = 5000 auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes disable_plaintext_auth = no mail_plugins = quota notify replication protocol imap { imap_client_workarounds = "delay-newmail " mail_plugins = quota imap_quota notify replication } protocol pop3 { mail_max_userip_connections = 3 mail_plugins = quota notify replication pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master info_log_path = log_path = mail_plugins = quota notify replication postmaster_address = sysadmin(a)example.com sendmail_path = /usr/lib/sendmail } userdb { args = /etc/dovecot/dovecot-usrdb-ldap.conf driver = ldap } passdb { args = /etc/dovecot/dovecot-passdb-ldap.conf driver = ldap } dsync_remote_cmd = ssh -l root vmail.example.com doveadm dsync-server -u%u replication_dsync_parameters = -d -N -l 30 -U plugin { mail_replica = remote:vmail@vmail.example.com } plugin { quota = maildir:User quota quota_rule = *:storage=5G quota_rule2 = Trash:storage=+3%% quota_warning = storage=75%% quota-warning 75 %u quota_warning2 = storage=90%% quota-warning 90 %u } service quota-warning { executable = script /opt/mail1.sh user = vmail unix_listener quota-warning { user = vmail } } service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service replicator { unix_listener replicator-doveadm { mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } user = root } service imap-login { service_count = 1 vsz_limit = 64 M } service pop3-login { service_count = 1 vsz_limit = 64 M } service replicator { process_min_avail = 1 } ssl_ca = </etc/pki/tls/certs/chain-2228.pem ssl_cert = </etc/pki/tls/certs/cert-2228.pem ssl_key = </etc/pki/tls/private/key-2228.pem syslog_facility = local1 ssl_protocols = !SSLv2 !SSLv3 -----------------------------------------------------------------------------

thanks very much urban. this was very helpful. i have around 12500 users spread over 3 independent servers each having around 4000+ users i am using qmailtoaster, vpopmail, spamassassin and dovecot. in future i am planning to consolidate all using a HA cluster. if it is ok with you could you kindly share some information about your email server configuration. if you do not wish to put it on the list then you can directly email me. 1) is your email volume high ? 2) server hardware to support 28000 users 3) mailserver software - exim or postfix ??. 4) antispam software like spamassassin if any also if you have faced any email re-download issues with dovecot sometimes randomly incase of pop3 users storing emails on the server ? thanks rajesh ----- Original Message ----- From: Urban Loesch [mailto:bind@enas.net] To: dovecot(a)dovecot.org Sent: Sun, 13 Sep 2015 09:33:14 +0200 Subject: Re: concerning dovecot settings for high volume server Hi, I have running dovecot with about 28k users.

restrict map-login by geoip?
by Terry Barnum 17 Sep '15

17 Sep '15

Is there a way to restrict my user logins from a set of IPs? For example, all my users are in the US so there shouldn't be any logins from other countries. Can I tell dovecot to restrict logins to a CIDR list of US IPs? Can someone point me to docs on how to set this up? I've searched but haven't found how to accomplish this. Thanks, -Terry Terry Barnum digital OutPost http://www.dop.com

New created users can not log in

Hi, I am using dovecot 2.2 for some time. All users on the system can log in using Horde Webmail. But now, after creating a new user on the server with <useradd -m username> this new user is not able to log in. Of course I have set a password for the new user. In the log file I can see: Sep 16 23:04:05 servername auth: gkr-pam: error looking up user information Sep 16 23:04:07 servername HORDE: [imp] [login] Authentication failed.

How to "Windows Authenticate"
by Mark Foley 16 Sep '15

16 Sep '15

I've been using Dovecot 2.2.15 as the IMAP server for Outlook (2010/2013) on Windows workstations for over 6 months with no problems. Dovecot is hosted on the office Samba4 AC/DC server. I have been using auth_mechanisms plain login, and passdb driver = shadow. What I'd like to do now is use the "Windows Authenticated" login so I don't have to have separate passwords for users logging into the Windows AD workstations and their Outlook clients. If anyone has actually done this I'd appreciate some tips. My various attempts have not been successful. Here is my current config: $ doveconf -n # 2.2.15: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.10.17 x86_64 Slackware 14.1 auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no info_log_path = /var/log/dovecot_info mail_location = maildir:~/Maildir passdb { driver = shadow } protocols = imap ssl_cert = </etc/ssl/certs/OHPRS/GoDaddy/Apache/c5fe0cc8242d6030.crt ssl_key = </etc/ssl/certs/OHPRS/GoDaddy/mail.ohprs.org.key userdb { driver = passwd } verbose_ssl = yes Thanks, Mark Foley

FreeBSD 10 & default_vsz_limit causing reboots?
by Rick Romero 15 Sep '15

15 Sep '15

Ok, So this is really more of an observation than anything else. I had a FreeBSD 10.1 server that was running great. Some SSL issue came up, or I upgrade Dovecot in ports - something occurred and the machine started rebooting randomly. It would run for 2 weeks, then reboot. It might run for 5 days and then reboot. So I started doing more FreeBSD upgrades, thinking it was a kernel issue. The reboots only increased. This weekend I started thinking I might actually be having hardware issues. But, since I don't have easy physical access to the box and it's REALLY under loaded, I figured what the hell and upraded to 10.2 on Sunday. I think it rebooted 4 times after that on Sunday, and then another 2 times Monday morning. Its worth noting that while I have crash dumps enabled, they don't seem to be occurring. So hardware is still a possibility. After the 2nd Monday morning reboot, I started to wonder if there was some sort of process issue. Besides the OS upgrades - I had been monitoring the Dovecot logs for when the process limits are reached, and increasing them. It's a 'big' box, and load is typically between .30 and .50. CPUs aren't overtaxed, and most of the memory is dedicated to ZFS. The reboots are so short, I've only received one 'down' alert due to them. So it's a conerning issue, but not really impacting production. On a whim I changed my default_vsz_limit (as I had been increasing every other limit but that) from 384M to 512M. The system hasn't rebooted in 24hours. Now that could be a coincidence, but I thought I'd at least put it out there. If you see anything weird in my dovecot config, let me know - My config was originally vpopmail, but over time I've migrated to SQL-only. root@romulus:/usr/local/etc/dovecot # dovecot -n # 2.2.18: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.2-RELEASE amd64 auth_master_user_separator = * auth_mechanisms = plain login auth_username_translation = %@ auth_verbose = yes default_login_user = dovecot default_vsz_limit = 512 M disable_plaintext_auth = no first_valid_gid = 89 first_valid_uid = 89 last_valid_gid = 89 last_valid_uid = 89 log_path = /dev/stderr login_greeting = Ready. login_trusted_networks = 172.16.100.0/24 mail_fsync = never mail_plugins = " quota zlib stats" mail_privileged_group = mail namespace compat { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } namespace inbox { inbox = yes location = prefix = separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-master-sql.conf driver = sql master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir quota_rule = Trash:storage=+10%% stats_refresh = 30 secs stats_track_cmds = yes } protocols = imap pop3 service anvil { client_limit = 3175 } service auth { client_limit = 3684 unix_listener auth-master { mode = 0600 } } service imap-login { process_limit = 1536 process_min_avail = 25 service_count = 1 } service imap-postlogin { executable = script-login rawlog /usr/local/etc/dovecot/lastauth-imap.sh user = vpopmail } service imap { executable = /usr/local/libexec/dovecot/imap imap-postlogin process_limit = 1536 } service pop-postlogin { executable = script-login /usr/local/etc/dovecot/lastauth-pop.sh user = vpopmail } service pop3-login { process_limit = 1536 process_min_avail = 15 service_count = 1 } service pop3 { executable = /usr/local/libexec/dovecot/pop3 pop-postlogin } service stats { fifo_listener stats-mail { mode = 0600 user = vpopmail } } shutdown_clients = no ssl_cert = </etc/ssl/mail.pem ssl_key = </etc/ssl/mail.key ssl_key_password = na userdb { driver = prefetch } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_max_userip_connections = 100 mail_plugins = " quota zlib stats imap_zlib quota imap_quota" } protocol pop3 { mail_max_userip_connections = 100 mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv }

Dovecot does not accept new connection with error "imap-login: Error: read(anvil) failed: EOF"
by Julien Fastré 14 Sep '15

14 Sep '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, First of all, thank you for the work the contributors are doing with Dovecot ! Dovecot is doing a great job ! I am encountering a problem with a configuration and, despite my search on the web, I do not find any solution for this problem. Dovecot seems to stop accepting new connection. The users : - - can not save sent messages to "Sent" folder (using Thunderbird) ; - - can not connect or retrieve message from webmail (using sogo or roundcube) In the log, I see this error : > Jun 30 13:54:53 mail dovecot: imap-login: Error: read(anvil) > failed: EOF Jun 30 13:54:53 mail dovecot: message repeated 2 times: > [ imap-login: Error: read(anvil) failed: EOF] (the message may be repeated more than 2 times) It happens... sometimes. Manually restarting the dovecot service make the software working again. By searching on the web, I regularly see this statement in logs : > dovecot: auth: Error: read(anvil-auth-penalty) failed: EOF like here : http://www.dovecot.org/list/dovecot/2010-November/054694.htm l But it doesn't seem to be the same problem as mine (anvil / anvil-auth-penalty). The problem happens during peak load. Sometimes it happens twice a week, sometimes it may spent two month without any problem (during holidays, I did not had any problem).

Need help on checkpassword userdb/passdb
by Mark Foley 13 Sep '15

13 Sep '15

I'm experimenting with checkpassword as an auth method for usedb and passdb (http://wiki2.dovecot.org/AuthDatabase/CheckPassword) I've set up the userdb and passdb *exactly* as the wiki suggests as the "standard way": passdb { driver = checkpassword args = /user/util/bin/checkpassword } userdb { driver = prefetch } I've created a checkpassword program that does receive the correct user and password from dovecot. And I am successfully authenticating with ntlm_auth and exiting with status 0. My debug output: AUTHORIZED: (null) USER: (null) userdb_uid: (null) userdb_gid: (null) arg1=/usr/local/libexec/dovecot/checkpassword-reply CMD: /usr/bin/ntlm_auth --username="mark" --password='mypass' ntlm_auth status: 0 Now, the wiki says 2 things that have me stumped: 1. It says that, "Dovecot calls the script with AUTHORIZED=1 environment set when performing a userdb lookup. The script must acknowledge this by changing the environment to AUTHORIZED=2, otherwise the lookup fails." As you can see from my program log, "AUTHORIZED" is not set. Why? Nor are any of the other environment variables mentioned in the wiki. I've listed all the environment variables that *are* passed to the program at the bottom of this message. 2. The wiki says, "Your program received a path to checkpassword-reply binary as the first parameter. Execute it." I did so as a fork() and then execve("/usr/local/libexec/dovecot/checkpassword-reply") How do I know it worked ... or failed? What am I doing wrong?

Dovecot CalDAV server
by Timo Sirainen 11 Sep '15

11 Sep '15

I've been once in a while over the years thinking about implementing CalDAV (and CardDAV) to Dovecot. It might be time to start that soon. Does anyone have any suggestions? So far my main goals would be: - scalable, of course - configurable storage (object storage, regular fs, maybe some key-value dbs, maybe storing as emails) - efficient indexes (potentially using key-value dbs? or maybe just local files. not sure yet what kind of indexing is needed) - have it work with dsync (= replication & migration) Some things I wonder about: - Maybe there is already some code out there that could be used to implement it faster? - Maybe even use something else besides C to implement it.. Then again that makes integration to Dovecot more difficult. - Is anybody interested in helping to develop this? :) I think I still have too much other work that I won't spend a lot of time coding it.. One thing that makes this easier is that Open-Xchange has already implemented a CalDAV server, so they can help to avoid the biggest design mistakes. (There are a couple of reasons why they'd want to replace that.)

My dovecot works fine against Active Directory 2003, but not against AD2008
by Fran 10 Sep '15

10 Sep '15

Hello, my dovecot installation has been working fine against AD till we upgrade from AD 2003 to AD 2008. As http://wiki2.dovecot.org/AuthDatabase/LDAP said, now I'm not able to connect AD through 389 port. The port 3268 works fine though. (...) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Error: master(imap): Auth request timed out (received 0/12 bytes) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Internal login failure (pid=4846 id=1) (internal failure, 1 successful auths): user=<<username>>, method=PLAIN, rip=<clientLAN_IP>, lip=<dovecotServer_IP>, TLS, session=<T+grMCsfqgAKHyZV> (...) Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<ZjyONSsf6QAKHyZV>): Connection appears to be hanging, reconnecting Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<T+grMCsfqgAKHyZV>): LDAP search returned multiple entries (...) Is there a technical reason for this problem? Does it exist any workaround? The use of Global Catalog (port 3268) is not a solution for me, since it misses many attributes. (ex. I use the field "initials" to set the quota and this field is not available through port 3268). I also noticed that, now, it uses any DC available in the domain, it doesn't care what I configured in "hosts = " parameter. This is using "hosts = dc03.domain:389": ----------------------------------------------- [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 22 0 <dovecotServer_IP>:55217 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 22 0 <dovecotServer_IP>:57645 <dc06.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 0 0 <dovecotServer_IP>:55216 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth It looks like it does a look up for other domains controller (I don't know how nor why) and it connect aleatory to any DC in my domain (in this case dc06.domain, but it changes any time), additionally to the configured one (dc03.domain).

Convert from Maildir to Mdbox
by J. Echter 09 Sep '15

09 Sep '15

Hi, i'd like to convert from maildir to mdbox. what would be the best way to do this? i have read the dsync part of the dovecot wiki but i don't get what i have to use for my setup. my dovecot.conf (the snippets i think would matter): mail_gid = 5000 mail_home = /DATEN/vmail/%d/%n mail_location = maildir:/DATEN/vmail/%d/%n/mail/ mail_plugins = " zlib" mail_uid = 5000 Thanks for your input.

[Dovecot] dsync replication errors
by Oli Schacher 09 Sep '15

09 Sep '15

Hi I'm trying to build a cluster of two servers with dsync replication (based on http://wiki2.dovecot.org/Replication) My test setup works fine for very simple tests, I can log in to both servers, copy a message to one of the servers and it successfully apperars in the other account. But, if I try to copy a large amount of messages at once to one of the accounts, my maillogs get flodded with errors(see below) and the mailboxes seem to get out of sync and messages are duplicated over and over again (I originally copied 100 messages and ended up with thousands in both mailboxes until I killed dovecot) I'd appreciate if someone could have a look at my config and tell me what I did wrong. dovecot.conf of both servers, they are identical except for the target ip in mail_replica: dovecot -n # 2.2.beta1 (070ca24e5846+): /etc/dovecot/dovecot.conf # OS: Linux

sieve_extprograms - double linebreaks at filtering
by Hajo Locke 09 Sep '15

09 Sep '15

Hello List, i have a problem when using sieve-plugin sieve_extprograms. I use dovecot 2.2.18 and bundled pigeonhole 0.4.6 (Ubuntu 14.04.3 LTS) i have enabled sieve_extprograms and vnd.dovecot.filter to send mail to user-defined script and get changed content back. My script previously was used with procmail and is working fine. Using same script with vnd.dovecot.filter leads to odd behavior. I already found out the problem itself: By sending Mailcontent to filter-programm it seems that sieve/sieve_extprograms is adding additional linebreaks to every line of complete mail. Please see this image to clarify: http://r31i.imgup.net/header8d56.jpg?l=de Every lineending got additional windows-lineendings, which leads to problems with processing scripts. Piping mails by procmail to same script is working without problems, because this mails are recieved "clean" without the "^M". this is part of dovecot.conf: plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } this is part of userscript ~/.dovecot.sieve: require ["fileinto", "vacation", "variables", "envelope", "imap4flags", "vnd.dovecot.filter", "subaddress"]; if address "to" "test2(a)example.com" { filter "my-script"; } my-script currently just recieves and saves raw-data, so i could find difference between sieve and procmail mails. What to do here? Is this a kind of bug of sieve/sieve_extprograms or i have to use additional parameters? Thanks, Hajo

Problems setting up SIS (duplicate files with same hash)
by Joe Beaubien 09 Sep '15

09 Sep '15

Hi everyone, I am currently trying to setup our next dovecot server (2.2.18) with SIS enabled, but I have enconutered 1 problem and 1 question: *1) Same attachment, different filenames* I have a feeling a misconfigured something (or forgot to do something) because SIS almost works, but not quite since 3 identical attachment take 3x the space (see end of email for my SIS config). For 3 the emails I sent with the same attachment, I got 3 seperate files with the same hash name but a different string following the dash: -rw------- 1 info info 2.6M Sep 5 11:14 e35083e3280a21c6aaabbae8cb23d54493f514a5-6a22711a7b05eb5509480000045c9bf4 -rw------- 1 info info 2.6M Sep 5 11:16 e35083e3280a21c6aaabbae8cb23d54493f514a5-6c22711a7b05eb5509480000045c9bf4 -rw------- 2 info info 2.6M Sep 5 11:18 e35083e3280a21c6aaabbae8cb23d54493f514a5-6e22711a7b05eb5509480000045c9bf4 drwx------ 2 info info 4.0K Sep 5 11:18 hashes For the record, the "hashes" subfolder has only 1 hash (e35083e3280a21c6aaabbae8cb23d54493f514a5) which perfectly matches the first part of the 3 filenames. *2) Saving attachments under a generic name or more flexible permissions?* It seems that dovecot saves the attachment with the username and group of the user who has received the email. Is it possible to have dovecot save the attachments as a generic user (like dovecot or dovenull) so that all my different users can share the same pool of attachments? Alternatively, is it possible to have dovecot save the attachment under more flexible permissions so that they can be shared between users? This would allow us to save alot of disk space. *Here is the SIS config I am using:* mail_attachment_dir = /data/emails/attachments #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} Any help would be very much appreciated. Thank you, Joe B

Dovecot and IPA
by Kanwar Ranbir Sandhu 08 Sep '15

08 Sep '15

Hello, I'm trying to get Dovecot to use GSSAPI for authentication. I have an IPA server on CentOS 7 with a bunch of my servers attached to the IPA domain, including the server running Dovecot. I've followed official documentation from Red Hat and read numerous wiki articles on how to configure Dovecot to get it to use GSSAPI correctly. I don't think I've done anything incorrectly, but it refuses to work. This is the error I'm seeing: mailman02 dovecot: imap-login: Disconnected (tried to use unsupported auth mechanism): user=<>, method=PLAIN, rip=1.1.1.1, lip=2.2.2.2, TLS, session=<QhWSqxofyAAKyAkM> I don't understand why no username is being passed. My mail client is Evolution 3.10.4. FYI, Dovecot does work fine using a user/password file. I'm just trying to switch it over to GSSAPI so that I can manage passwords from one system. Any help would be appreciated. Regards, Ranbir -- Kanwar R.S. Sandhu

Multiple vacation
by Michele Locati 08 Sep '15

08 Sep '15

Hi all I'm using Dovecot 2.2.9 and I'm having problems configuring multiple vacation actions. The problem is that I'd like to have two different senders and two different messages, selecting the correct case by the recipient email address. I mean, if someone writes me to my email address "to-address1(a)example.com" I'd like to answer from "from-address1(a)example.com" with the message "TEST 1". If someone writes me to my email address "to-address2(a)example.com" I'd like to answer from "from-address2(a)example.com" with the message "TEST 2". Here's my script: require ["fileinto","vacation"]; vacation :addresses ["to-address1(a)example.com"] :from " from-address1(a)example.com" text: TEST 1 . ; } vacation :addresses ["to-address2(a)example.com"] :from " from-address2(a)example.com" text: TEST 2 . ; But the vacation filter doesn't work, and I see this message in the log file: main script: line X: error: duplicate vacation action not allowed (previously triggered one was here: main script: line Y). Is there a way to allow multiple vacation actions? Thank you Michele
