[Dovecot] LDA/Sieve and vacation: empty envelope sender
by Roberto Puzzanghera 10 Jul '11

10 Jul '11

Hello everyone, while testing a vacation/reject sieve rule I get: lda(sender(a)mydomain.xyz): Error: sieve: envelope sender address '<>@mail.domain.xyz' is unparsable follows an empty Return-Path: <"<>"@mail.domain.xyz> and the reject of the message itself by the recipient's MTA (syntax error). Unfortunately I had no luck when googling for similar issues, after a couple of hours of debugging. qmail/vpopmail dovecot 2.0.12 pigeonhole-0.2.3 Thanks in advance for any hint Roberto Puzzanghera

Hey all, has anyone ever successfully implemented some form of OTP system with dovecot? Im looking at setting up an OATH/HOTP-TOTP based OTP for our services, but the webmail service (which uses dovecot) is a difficult one. Any info on implementations would be appreciated, Regards, Cor

Another question: All my user information are keeped inside LDAP using qmail.schema. Can dovecot pop3 look into ldap an return information about user mail directory, etc .... ? Thanks in advance.

[Dovecot] IMAP not working remotely
by Ondřej Bouda 09 Jul '11

09 Jul '11

Hello, I am trying to set up Dovecot 2.0.9 on Fedora 14. The problem I would like to ask for resolution is that IMAP is not working when connecting to the server from another network. More precisely: - POP3 is working entirely OK, - IMAP is working OK when clients are connecting using local network addresses, like 192.168.0.100, - when a client connects from outside, thus using remote IP address, or even from the server itself using the remote IP address of the server, the following happens: the client correctly connects, but the server sends no greeting (neither the configured login_greeting nor the server IMAP capabilities) and does not respond to the commands. In the server log, I get the following record a while after trying to connect (and actually trying to login): Jul 08 23:24:16 imap-login: Info: Disconnected: Inactivity (no auth attempts): rip=<remote-server-address>, lip=192.168.0.100 Both routing and firewall are OK. The client really connects to dovecot (hence the log message), as seen from a telnet session: Trying a.b.c.d... Connected to example.tld (a.b.c.d). Escape character is '^]'. (and then nothing else) The most confusing for me is the fact that POP3 is configured quite the same and works fine, as well as IMAP on the local network. I tried to change address in the inet_listener imap configuration, but if a wrong address setting was the cause, the client would not get connected at all. As I have spent a pretty long time unsuccessfully searching for a cause, I am asking for some help. Thanks for your time, Ondrej Bouda dovecot -n output follows: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.11-83.fc14.x86_64 x86_64 Fedora release 14 (Laughlin) ext4 auth_mechanisms = plain login cram-md5 digest-md5 ntlm disable_plaintext_auth = no first_valid_gid = 502 first_valid_uid = 502 last_valid_gid = 502 last_valid_uid = 502 log_path = /var/log/dovecot login_greeting = Welcome mail_location = maildir:/var/mail/virtual/%d/%n passdb { args = scheme=plain username_format=%u /etc/dovecot/passwd driver = passwd-file } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = dovecot-auth } service imap-login { inet_listener imap { address = * port = 143 } } service pop3-login { inet_listener pop3 { address = * port = 110 } } ssl = no userdb { args = username_format=%u /etc/dovecot/passwd driver = passwd-file } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv }

[Dovecot] auth_username_chars question
by Linda Walsh 09 Jul '11

09 Jul '11

I notice there is a space after the = in the default setting: #auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ Is that space part of the syntax or required? If not, does that mean 'space' is included in the default list of allowed characters? If not, then is the space after the '=' required? -- If not, the implication would seem to be that space is 'ignored'. If that's the case, how does one include 'space' in the list of allowed characters? Also, how does one include the "\" character in the list of allowed characters? I.e. is anything accepted, literally, after the first non-space char after the '=' sign? I.e. any spaces after the first non-space char would be taken as valid character, and '\' would also be a literal character? (not that'd I'd be using windows's clients or anything that would, on occasion, pass "DOMAINAME\user" as the calling user trying to log into a 'user' account....or anything....*ahem*...) Overrode it w/some hard-coded hacks, but would like dovecot to me more robust and handle weird input and do the right thing with it (I know that's always a challenging concept for some people, since the answers and ability to arrive at 'correct' is always 'contextual', and so many people want absolute rules that apply all the time in all cases, but...I think thats a diagnosable psychological condition ;-) ).

08 Jul '11

I am receiving a lot of error messages dovecot-auth: gkr-pam: error looking up user information for: <user> Unfortunately, I do not see the IP of the remote client, trying to break in. Is there any possibility to get it ? Would be useful to block the IP. -- View this message in context: http://old.nabble.com/dovecot-auth%3A-gkr-pam%3A-error-looking-up-user-info… Sent from the Dovecot mailing list archive at Nabble.com.

Hello Is it possible to configure Dovecot (2) to "redirect" IMAP connexions to IMAPS ? I know it would be possible with ipfw on the server but I wonder if dovecot has such capability. thanks

[Dovecot] Possible bug in shared namespace variable?
by Tom Clark 08 Jul '11

08 Jul '11

As you would have seen earlier I've created a shared mailbox with the following namespace: namespace { type = shared separator = . prefix = Shared.%%n. location = maildir:/var/vpopmail/domains/%%d/%%n/Maildir:INDEX=~/Maildir/Shared/%%n subscriptions = no list = children } This works perfectly, but for some reason the %%n variable in the location maildir is blank. Everywhere else %%n is used works (e.g. the prefix and INDEX). This means for the shared mailbox under support(a)mailbox.com I get a folder Mailder in the domain folder: /var/vpopmail/domains/mailbox.com/Maildir instead of /var/vpopmail/domains/mailbox.com/support/Maildir. Has anyone else come across this?
