Happy holidays! I am experiencing an issue when trying to check my mail
using IMAP. with Dovecot I have tried checking my mail using a full GUI
client (Thunderbird) and telnet. Both times I get disconnected before all
of my messages can be downloaded and I see an error in my mail log. Here
are the details:
[root at cust19-1-prod-domain userqa]# dovecot --version
2.0.9
[root at cust19-1-prod-domain userqa]# dovecot -n
# 2.0.9: /etc/dovecot/dovecot.conf

disable_plaintext_auth = no
login_trusted_networks = 172.19.136.0
mail_location = maildir:~/Maildir
mail_max_userip_connections = 100

mmap_disable = yes
passdb {

}
protocols = imap
ssl = no
userdb {

driver = passwd-file
}
[root at cust19-1-prod-domain userqa]#
i try to check my mail:
username at ops1-1-domain:~$ telnet cust19-1-prod-domain imap

I get some binary output and some mail headers, but then it crashes..
Not sure if you guys want to see all of the extremely verbose output, so I
put it at the end of this message. The last messages that it processes is a
message with an Excel spreadsheet attached to it (a .xlsx file)
i enabled core dumps:
echo 'DAEMON_COREFILE_LIMIT="unlimited"' >> /etc/sysconfig/dovecot
Now I see this in /var/log/maillog:
2012-12-25T17:53:47-08:00 cust19-1-prod-domain dovecot: master: Error:
service(imap): child 11265 killed with signal 11 (core dumped)
core dumps are being written here, but they're empty:
[root at cust19-1-prod-domain userqa]# pwd
/mnt/mail/userqa
[root at cust19-1-prod-domain userqa]# ls -lh
total 20K
-rw------- 1 userqa userqa 0 Dec 25 17:52 core.11111

drwx------ 7 userqa userqa 4.0K Dec 25 17:58 Maildir
[root at cust19-1-prod-domain userqa]#
What should I try now? Is it possible that Dovecot is having difficulty
processing the attachment file? If I delete this user's mailbox file and
send basic text e-mail to the user I can read/retrieve them just fine..
there only seems to be an issue when this message with its attachment
arrives. The attachment seems small in size:
Content-Disposition: attachment; filename="report_amex.xlsx"; size=20527;
That means the attachment is 20527 bytes, correct?
Thank you for any suggestions/help you can offer!
Here's the message that it seems to be having issues with:
