syncing imap servers with imapsync

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



hello list,

 I am attempting to sync two imap servers using the imapsync perl script. It seems handy and easy.


Here's what happens when I try to do this:

#
# Postfix master process configuration file.  For details on the format
# of the file, see the master(5) manual page (command: "man 5 master").
#  -o smtpd_sasl_auth_enable=yes

#smtps     inet  n       -       n       -       -       smtpd
virtual   unix  -       n       n       -       -       virtual
lmtp      unix  -       -       n       -       -       lmtp

          -o smtp_data_done_timeout=1200
          -o smtp_send_xforward_command=yes

I can log into both imap servers without any problem. Server1 is a zimbra server and Server2 is a plain vanilla postfix setup with courier imap. I believe the problem is with courier authlib and the advertised capabilities of that server.


Info: host mail.example1.com says it has NO CAPABILITY for AUTHENTICATE LOGIN


This is my authmodulelist on server2.


authmodulelist="authuserdb authpam authpgsql authldap authmysql authcustom authpipe"

This is all I see in the postfix logs on the second server when the authentication failure happens:


Dec  3 22:54:59 li135-81 imapd: Connection, ip=[::ffff:69.164.220.81]
Dec  3 22:55:01 li135-81 imapd: LOGIN FAILED, user=bluethundr, ip=[::ffff:69.164.220.81]
Dec  3 22:55:06 li135-81 imapd: Disconnected, ip=[::ffff:69.164.220.81], time=7
Dec  3 22:55:15 li135-81 imapd: Connection, ip=[::ffff:127.0.0.1]
Dec  3 22:55:15 li135-81 imapd: LOGIN, user=bluethundr@xxxxxxxxxxxx, ip=[::ffff:127.0.0.1], port=[57141], protocol=IMAP
Dec  3 22:55:15 li135-81 imapd: LOGOUT, user=bluethundr@xxxxxxxxxxxx, ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=94, sent=460, time=0

I'm thinking I need to find a way for server2 to authenticate via plaintext for this to happen. 

I'd appreciate any advice you might have.

thanks in advance
tim
