[Dovecot] vpopmail + dovecot-lda doubling deliver messages
by Juliano Nascimento 29 Jul '11

29 Jul '11

We use qmail + vpopmail + dovecot, limits and alias are in vpopmail mysql database, it has worked ok. The .qmail-default: | /data/vpopmail/bin/vdelivermail '' bounce-no-mailbox | /var/qmail/bin/preline -f /usr/local/dovecot/libexec/dovecot/deliver -d $EXT@$USER When you send a message to alias works OK. The problem that is happening that is sent to asdf(a)domain.com asdf(a)domain.com he is doubling the email. Come the email that you sent / wrote an email and more with nearly no head, no matter. Searching is very realized that something related to Deliver the dovecot. Can you help us? Tips? Thank you all.

[Dovecot] vpopmail and proxy-* parameters (again)
by Martin Spütz 29 Jul '11

29 Jul '11

Hello, I'm using a patched version of passdb-vpopmail.c to use CRAM-MD5 on the director. Today I updated the patch to 2.0.13. It may be an edge-case but I think it could be useful for somebody else. Greetings Martin

This only happens on recipients that are not first on the recipient list. Best regards, -Boris PS - Apologies to the list if this mail produces an out of thread message as I posted the original message as a non-member (needing moderator approval) and I am now a member.

[Dovecot] want only usder in userfile/passfile and use to login user@domain
by Erik - versatel 28 Jul '11

28 Jul '11

After adding: auth_username_format=%Lu the %d domain is unfolleded correctly. (and not empty anymore) Maybe a good idee to make a remark in the text Virtual Users about that. I use: passdb: driver: passwd-file args: /etc/dovecot/vhosts/%d/etc/shadow userdb: driver: static args: uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u In the password-file (shadow) i have to add users in the form user@domain. I want to add users in the form user I have also tryed not a static userdb but a real one; see example Dynamic-passwd locations. To get this working i had to add mail-uid and mail-gid. But still it has the same form user@domain and not user Can anybody tell my how to get ride of the domain part in the passwd en userfile. I still want the user to login with user@domain Thanks.

[Dovecot] National characters

Hi, I upgrade my server an I have dovecot 2.0.9 (on RedHat 6) and my user uses Thunderbird 5.0 (on Windows XP). I use authentication via LDAP (Windows server 2003 AD). When users use in password diacritic marks (ą,ć,ę,ł,ń,ó) authentication failed. For example when user test have password: Sierpieńłą*123 in log file item appears: localhost dovecot: auth: ldap(test,192.168.0.68): invalid credentials (given password : SierpieDB#005*123) What can I do? Thanks

[Dovecot] dovecot quota feature request
by Shing 28 Jul '11

28 Jul '11

Hi all, I'm going to implement before queue quota check with postfix to prevent bounce mail, the quota information is stored into mysql using dovecot quotadict, it would be nice that dovecot can have an option to switch the quota check with (used space < quota) instead of (used space+mail size < quota), so that i can write a simple sql statement to check_recipient_access to reject those mail, thanks.

[Dovecot] Store quota on passwd-file?? Not work
by Sébastien FOURCADE 28 Jul '11

28 Jul '11

Hello all, I have installed Dovecot 1.2.15 and Postfix 2.7.1 on my Debian 6.This install no include MySQL, I prefer to store Password/User in a file... File /etc/dovecot/passwd contains :user2@domain.com:{CRAM-MD5}::::userdb_mail=maildir:~/Maildir userdb_quota_rule=*:bytes=300M File /etc/dovecot/users :user2@domain.com::3000:3000::/home/vmail/domain.com/user2/:/bin/false:: What is the correct syntax for my file to use a different per-user quota ? This example not work on my Dovecot :user2@domain.com:{CRAM-MD5}:3000:3000::/home/vmail/domain.com/user2::userdb_mail=maildir:~/Maildir userdb_quota_rule=*:storage=200Muser2@domain.com:{CRAM-MD5}:3000:3000::/home/vmail/domain.com/user2::userdb_quota_rule=*:bytes=200M Thx.

[Dovecot] set delay between pop3-logins
by tonjg 28 Jul '11

28 Jul '11

I'm using dovecot 1.1.8 on a raq4 server running centos 4.8 Is it possible to set a time delay between all dovecot pop3-logins? say 20 - 30 seconds for example? My reason is I want to thwart the constant login attempts from hackers hunting for an open relay. It's no good blocking the ip address because every hack attempt comes in from a different address. I'm the only user on the server so no-one else would be affected by such a delay. Thanks for any pointers -- View this message in context: http://old.nabble.com/set-delay-between-pop3-logins-tp32134037p32134037.html Sent from the Dovecot mailing list archive at Nabble.com.
