[Dovecot] Problem with messages with long lines

[ZMA - Emiliano Mariño]

Hello dear mailing list readers,

 

Recently I am experimenting a problem trying to retrieve messages over a
POP3 protocol.

Everything goes right until the POP3 client tries to retrieve a message that
contains one or more long lines – lines as long as 3000 characters or even
more.

The client (Outlook 2003 and 2007) stops on that message until timeout.

I have opened a connection manually to see what happens, and when I issue
the RETR command on one of these messages, dovecot informs the message size
and then nothing else. No message sending.

Any other message works fine; I get the message size and next the message
itself.

I have upgraded to version 2.0.1 but I still get the same behavior.

No error is reported on the server side. Logs indicate that everything is
just fine.

 

Any advice on how to solve this would be very appreciated.

 

Here is the dovecot 2.0.1 configuration:

 

############################################################################
#######

 

# 2.0.1: /etc/dovecot/dovecot.conf

# OS: Linux 2.6.23.1-42.fc8 i686 Fedora release 8 (Werewolf)

auth_username_chars =
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@&

auth_verbose = yes

disable_plaintext_auth = no

listen = *

login_greeting = Dovecot DA ready.

mail_access_groups = mail

mail_location = maildir:~/Maildir

passdb {

  args = username_format=%n /etc/virtual/%d/passwd

  driver = passwd-file

}

passdb {

  driver = shadow

}

service auth {

  user = root

}

ssl_cert = </etc/httpd/conf/ssl.crt/server.crt

ssl_cipher_list = ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

ssl_key = </etc/httpd/conf/ssl.key/server.key

userdb {

  args = username_format=%n /etc/virtual/%d/passwd

  driver = passwd-file

}

userdb {

  driver = passwd

}

verbose_proctitle = yes

protocol pop3 {

  pop3_client_workarounds = outlook-no-nuls oe-ns-eoh

  pop3_uidl_format = %08Xu%08Xv

}
