[Dovecot] Empty/corrupt mail leads to duplicate delivery
by Marc Herbrechter 29 Oct '08

29 Oct '08

Hi, when the attached mail was stored in a maildir, fetching mail via POP3 lead to multiple delivery of mails in that maildir to the client (Outlook). I replaced the domain with dots. This is the dovecot configuration: --snip-- protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no ssl_cert_file = /etc/ssl/dovecot/server.pem ssl_key_file = /etc/ssl/dovecot/server.key mail_location = maildir:~/.maildir protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { mechanisms = plain passdb pam { args = "*" } userdb passwd { } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } --snip-- Version: dovecot-1.1.4-r1 (Gentoo) Gentoo applies the attached "expire" patch. I tried to reproduce the behavior, but when I send an empty mail via telnet, nothing happens. The box is running Amavis, don't know if that helps. -- Mit freundlichen Grüßen, with kind regards, Marc Herbrechter <mh(a)zebroc.de>

[Dovecot] Keep the email on the server
by Rubens A. Mascari 29 Oct '08

29 Oct '08

Hello, I migrate my server POP3/IMAP recently the Courier-IMAP for Dovecot and am having problems when the user configures your e-mail client to leave a copy of mail on the server. All mail in the inbox, are brought all the time that you check your mailbox input via POP3, causing a large traffic of unnecessary data every time. In my opinion you should bring only the new mail, unread. Can you tell me if this is a configuration issue on Dovecot? Thank you all -- Att.

[Dovecot] cannot use password-file for userdb
by Albert E. Whale 29 Oct '08

29 Oct '08

OK, I am attempting to use the userdb connection to facilitate per user migration to Maildir format from mbox. Here's the first user: more /home/dovecot.passwd health:$1$MCtvt/Tz$FmKqU/cbWlBhKnhc5W.Ko.:1152:1152:/home/health:userdb_mail=maildir:~/Maildir The configuration was set up as: userdb passwd { } I changed this to: userdb passwd-file { args = /home/dovecot.conf } And unfortunately the dovecot daemon dies after successfully launching.

[Dovecot] Quick question regarding autocreate plugin
by Jakob Curdes 29 Oct '08

29 Oct '08

Hello, just a quick question: if I want to use the autocreate plugin with 1.1.5, I have to compile it "by hand", right? How do I do that? Can I adapt a Makefile from another plugin? JC

[Dovecot] 1.1.5 abort with mal-formed address in header

[Dovecot] mbox to Maildir conversion
by Albert E. Whale 28 Oct '08

28 Oct '08

I've been running a mbox solution using UW's IMAP server. I've run it for years. Now do to heavy message volumes, I've decided to to take the plunge to convert to the Maildir format. I am currently testing a single user, and have successfully converted the mail messages from mbox to Maildir format, and now I am setting up the procmail tool to place the messages into the correct folder. I have been following the http://wiki.dovecot.org/Migration/MailFormat formula, but now have a question. New Messages are now being placed into the ~user/Maildir/new folder. However, when I attempt to retrieve those messages, Dovecot does not find them. Why not? -- Albert E.
