This kind of behavior looks like a network issue. > You called it. We access the server over the Internet. How did I forget to provide that small detail? However, that's not the slowness I speak of. Perhaps a better term is long delay, like waiting on some timeout, before message loadding (in symptom 1., above). So are there parameters to tune, that will make dovecot behave nicer? I do not believe this to be connectivity outages between our clients and the server. For one, we never experienced these symptoms with UW-IMAP. I just duplicated the stall on copying to Sent folder. This is probably the more prevalent, and annoying of the two problems. facts: * There was only one active client. * The client was T'bird, v1.5.0.10, running on XP. * This particular test had a 3Mb attachment. * The mail was delivered immediately to the single, remote recipient (after a ~20 seconds of 3Mb upload). * The "Copying to Sent Folder" dialog stayed up for (no exaggeration) 15-minutes, and then completed; the message is in the Sent folder now. suspicion, from months of experiencing the behavior: * Attachments are usually involved. How does the config look? Are the mbox lock settings appropriate? I was somewhat shooting in the dark there. * Sendmail 8.13.6/8.13.6 * $sudo sendmail -bt -d0.10 < /dev/null | grep HASFLOCK OS Defines: BSD4_4_SOCKADDR HASFCHOWN HASFCHMOD HASFLOCK mbox_read_locks = flock mbox_write_locks = flock What else can I provide? netstats? tcpdumps? Are there logs/debugging appropriate to enable? Thanks for any ideas, Danno

[Dovecot] Method to globally limit network access
by Marcus O. White 05 May '07

05 May '07

G'day All, I am new to dovecot. I've run across the "allow_net" to restrict access on what seems like a per user basis. Is the a way to global limit access to one or more networks? Marcus O.

[Dovecot] Converting Courier mailboxes to Dovecot
by Andy Shellam 05 May '07

05 May '07

Hi, I have around 100 mailboxes (maildirs) to convert from Courier IMAP (4.1.3) to Dovecot. (From a recent backup) I've tested a few mailboxes on Dovecot 1.0.0, and while the client doesn't notice any difference (at least in Thunderbird) I'm hoping to get rid of the old Courier folders and convert any useful information they may have into Dovecot. I've tried Timo's migration script (http://www.dovecot.org/tools/courier-dovecot-migrate.pl) but it fails at line 230 with a "no file/directory" error. At that line, it appears to be finding Courier's keywords folder (courierimapkeywords), and looking for a file called ":list". However in my mailboxes, there's no file by that name, only what looks like a set of standard IMAP filenames, most of which are empty files. If I can't salvage anything useful, is there any adverse effects to me deleting all the "courier*" files/folders from each mailbox and subfolders so when the client connects back when Dovecot's running, it creates it's own UIDs and keywords etc? Thanks Andy.

[Dovecot] Help with LDAP authentication - user / user+domain
by Venilton Junior 04 May '07

04 May '07

Hello Folks, I've my dovecot working well and authenticating in my ldap servers. But I'd like configure my users to authenticate in two ways. One is just submitting the username and the other one is providing user(a)domain.com . I'm moving from a cyrus-imap solution to dovecot and I've implemented it with VD domains. But nowadays I still have one domain at my servers. So to no cause to much impact to users, I'd like to provide this two ways of authentication. Here follows my dovecot-ldap.conf: hosts = localhost dn = uid=admin,ou=administrators,ou=topologymanagement,o=netscaperoot dnpass = XXXXXX auth_bind = no ldap_version = 3 base = dc=domain,dc=com deref = never scope = subtree user_attrs = mail,homeDirectory,,,,quota=quota=maildir:storage user_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) pass_attrs = mail,userPassword pass_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) default_pass_scheme = SSHA user_global_uid = 100 user_global_gid = 101 My logs: Apr 30 13:47:58 server dovecot: auth(default_with_listener): client in: AUTH 1 PLAIN service=POP3 lip=xxx.xxx.xx.xx rip=xxx.xx.xxx.xxx resp=AGpveWNlLm1hcmlhbm8AbWFrdHVi Apr 30 13:47:58 server dovecot: auth(default_with_listener): ldap(user.test,xxx.xx.xxx.xxx): pass search: base=dc=domain,dc=com scope=subtree filter=(&(objectClass=VirtualMailAccount)(mail=user.test)(accountActive= TRUE)(delete=FALSE)) fields=mail,userPassword Apr 30 13:47:58 server dovecot: auth(default_with_listener): ldap(user.test,xxx.xx.xxx.xxx): unknown user Apr 30 13:47:59 server dovecot: auth(default_with_listener): client out: FAIL 1 user=user.test Apr 30 13:48:05 server dovecot: pop3-login: Aborted login: user=<user.test>, method=PLAIN, rip=xxx.xx.xxx.xxx, lip=xxx.xxx.xx.xx If I provide user.test(a)domain.com works fine.

[Dovecot] Sieve not recognizing keywords
by Alexander Hoogerhuis 04 May '07

04 May '07

First, I've been lurking and using dovecot for a few years now and I've always liked it, great piece of software! :) I've finally decided to clean up my act here and get virutal users and get postfix (2.3), dovecot (1.0.0) and deliver to play nice, using postfixadmin. I have it 99% there, but one thing is left: When I receive mails, deliver finds my virtual home dir and then tries to compile the sieve script (converted from procmail with the script mentioned in the wiki), and then always bums out on this: sieve parse error: line 3: Unsupported features in require line and line 3 looks like this: require ["fileinto","regex","envelope","vacation"]; which should be fine? Then I googled around and found this thread from january: http://www.dovecot.org/list/dovecot/2007-January/018376.html Which made it sound like the sieve plugin 1.0.0 had a bug that got fixed in 1.0.1. I am doing all of this on Gentoo, so I decided to just redo the ebuild so that I got the dovecot 1.0.0 ebuild, but with the sieve plugin 1.0.1. Aparently I get the same error and now am at a loss here. Any pointers? -A

[Dovecot] Testing IMAP clients with Dovecot, problems with MacMail
by Stewart Dean 04 May '07

04 May '07

I've been testing my user community's IMAP clients when I try to login and then transfer a big message from the inbox into a folder in an overquota folder directory. I am using native filesystem quotaing in AIXV5.3 with UWIMAP and comparing my results with what I see with Dovecot 1.0.0. (My Dovecot built without any plugins or quota extensions) Everything matches/works except for Mac Mail under SSL with Dovecot.. Mac Mail: 1) with UWIMAP, login and mailbox load goes OK, then the illegal overquota xfer fails (as it should) with a popup reading 'Message could not be moved', with (port 993) and without (port 143) SSL 2) with Dovecot, 1) login and mailbox load goes OK to port 10143, plain listen, and the illegal xfer correctly fails as it should with a popup messge under a plain connection, but 2) When the port number is set to the Dovecot ssl_listen port and the SSL box is checked, Mac Mail doesn't bring up the inbox and folders...it acts like it can't connect. Has anyone else seen this behavior, and is there a fix? Mac Mail is also known as Mail.app. I am testing it at 1.3.11 and 2.1.1. In the July '05 archive, I found this: > It looks like Mail.app treats "non-standard" ports differently. On the > standard port (993), the "SSL" option seems to do pure SSL; but with > another > port specified, it does clean-plus-starttls (and hence fails horribly, > because > it's talking to a pure SSl service) Is there anything I can do to get MacMail to behave correctly? Or will it clear up when I shut down UWIMAP and give Dovecot the default ports. A Bronx cheer for Mac Mail........ My thanks in advance, S. Everything else I tested behaves...for anyone that's interested....... ================ Over Quota Xfer results ==================== Insecure Pine from Unix login shell: refused by both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps. It is presumed that this will be used from within an SSH session to secure the transmission. Webmail (horde, insecure and secure) : refused by both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps. PC: TBird 1.5, 2.0, Sea Monkey and Netscape 7.2: get a popup with both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps, both secure and insecure Mac: Seamonkey: ditto, same as PC Sea Monkey Mac Mail or Mail.app only works insecure, as per above

[Dovecot] Does dovecot do any address checking or referring back to a server?
by Wade Smart 04 May '07

04 May '07

This is a dovecot question so bear with me. I just upgraded to Ubuntu 7.04 from 6.06. I used fetchmail and postfix but not dovecot on 6.06. Fetchmail retrieved my mail and postfix put it in my maildir. I used Evolution to access the maildir directly. I setup Evolution to send mail directly as well. With this move I decided to go the extra step and get dovecot working. With some help on this form, I did that. But, I immediately started having trouble with getting my mail. Fetchmail is retrieving it but postfix keeps not processing for some reason. Im geting these error message: May 2 17:14:11 wadesmart postfix/qmgr[14778]: 6D4AD14286F3: to=<wadesmart(a)mail.wadesmart.com>, orig_to=<wade@localhost>, relay=none, delay=9331, delays=9307/25/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to smtpout.secureserver.net[64.202.165.58]: Connection timed out) The thing is - Im not sending mail at all through postfix. So my question is, I know that dovecot only serves up email to a mail client but, does it do something that I have totally missed that would some how or some way refer mail back to a server? Is there some type of address check or something going on? I know Im grasping at straws here but, I have been unable to get help from the postfix list or any list for that matter so if I can eliminate one more piece of the puzzle, all the better. Thanks.

[Dovecot] Dovecot SASL for postfix: Client host rejected: when relaying using POP mail client
by Nad 03 May '07

03 May '07

Hi everyone I have setup an ISP style mail system using postfix, dovecot, squirrelmail and mysql on ubuntu server 7.04. Everything seems to be working fine with sending recieving emails but relaying on submission service (port 587). I want to allow any client to be able to relay as long as they AUTH using dovecot SASL and are valid users regardless of what IP/host they come in from. I have a feeling that the submission service is not able to make use of dovecot sasl-auth. Here is what I have in my master.cf to enable submission service: submission inet n - - - - smtpd -o smtpd_enforce_tls=no -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject My main.cf file looks like this: queue_directory = /var/spool/postfix command_directory = /usr/sbin daemon_directory = /usr/lib/postfix mail_owner = postfix myhostname = mail.domainname.tld mydomain = domainname.tld myorigin = $myhostname inet_interfaces = $myhostname inet_protocols = ipv4 mydestination = $myhostname unknown_local_recipient_reject_code = 550 mynetworks_style = host mynetworks = aa.bb.cc.dd relay_domains = $mydestination alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases sendmail_path = /usr/sbin/sendmail newaliases_path = /usr/bin/newaliases mailq_path = /usr/bin/mailq setgid_group = postdrop transport_maps = proxy:mysql:/etc/postfix/mysql/transports.cf virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql/domains.cf virtual_mailbox_base = /srv/mail virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql/accounts.cf virtual_alias_maps = proxy:mysql:/etc/postfix/mysql/forwardings.cf, proxy:mysql:/etc/postfix/mysql/emails.cf virtual_minimum_uid = 8 virtual_uid_maps = static:8 virtual_gid_maps = static:8 dovecot_destination_recipient_limit = 1 smtpd_use_tls = no smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth strict_rfc821_envelopes = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_non_fqdn_recipient, reject_unknown_recipient_domain When I try to relay using Outlook, I see the following message in the mail.log: May 3 00:36:33 mail postfix/smtpd[10004]: connect from cable.company.client.hostname.com[12.34.56.78] May 3 00:36:33 mail postfix/smtpd[10004]: NOQUEUE: reject: RCPT from cable.company.client.hostname.com[12.34.56.78]: 554 5.7.1 <cable.company.client.hostname.com[12.34.56.78]>: Client host rejected: Access denied; from=<postfixuser(a)domainname.tld> to=<someone(a)anotherdomainname.tld> proto=ESMTP helo=<mycomputer> May 3 00:36:33 mail postfix/smtpd[10004]: disconnect from cable.company.client.hostname.com[12.34.56.78] May 3 00:36:33 mail dovecot: pop3-login: Login: user=<postfixuser(a)domainname.tld>, method=PLAIN, rip=12.34.56.78, lip=aa.bb.cc.dd May 3 00:36:33 mail dovecot: POP3(postfixuser(a)domainname.tld): Disconnected: Logged out top=0/0, retr=0/0, del=0/626, size=27305010 I have tried several options for the last 2 days but have not been able to get past in relaying email for valid-users from any/all client hosts.
