ERR Read failed with POP3

[aaronsca]

Running Fedora Core 4 and Scalix 10.0.1.21, we have a problem with accessing a mailbox via POP3. Specifically:

[root@boi-u1]# telnet email.zipsearch.com 110

Accessing the account from IMAP and Webmail both work fine. Only POP3 access appears to be broken. I was hoping it was a corrupted mailbox that omscan could fix, but it doesn't look that way:

[root@elctrbz87]# omscan -A -U "/CN=EmailArchive"

Oddly enough, the CLI commands omlogon, omlist, omread and omlogoff all appear to work correctly as well.

The plot thickens. It appears as though going through the CLI commands omlogon, omlist, omread and omlogoff finxed whatever was breaking POP3 and it is working now. I guess I'll be setting up a cron job to do this until we find the root cause. Weird.

Just thought i would add to this and let you know you're not alone in this strangeness, it's just occured with one of my users.

Thanks for the fixness advise, i just hope it doesn't happen again.

Are you seeing anything in /var/opt/scalix/logs/fatal that could provide more information?

Thanks,
Don

Did anyone figure this out?
I'm having the same problem.

Please see Don's question immediately above your post.

Occurring for another one of my users, seems there's nothing in the fatal log.

It only seems to occur when the user is using pop3 and has 1000+ mails to retrieve.

Although the omlogon / omlist / omread 1 / omlogoff didn't solve it this time, it required logging in to swa and flagging ALL mail as read

I believe this is fixed in the 10.0.5 patch. Please see http://www.scalix.com/community/viewtopic.php?t=5051
