Squirrelmail Error 354

Hi all,

I have a box on Freebsd running Exim,Courier & Squirrelmail for mail
services and apache web server.

My problem is,whenever I change the cisco switch port the box is connecting to,to different with exactly the same settings (speed and duplex modes),I always get this squirrelmail error when trying to send mail:

ERROR:Message not sent. Server replied: 354
I finally get to send mail after a few tries a factor that makes sending mails extremely slow even for mail clients like 'autlook'.The condition resumes back to its normal working operation immediately I go back to its former switch and port.A point to note here is, all other services like the web server in the box are not interfered with by any of this changes and run as normal...mail is the only service affected.In both cases the box and the switch are always in sync - duplex and port speed options.

I cant seem to find anything useful from the mail logs to assist me in sorting and now I have to stop this switchport-boxethernet 'bond' coz I have to upgrade the current switch.

Anyone with suggestions on what could be causing this and how I would go about in sorting it...please assist me.

Just found something - I get this from the courier logs immediately after the 354 squrrelmail errors - could be useful:
imapd: Failed to create cache file: maildirwatch ('mailuser'@'')
All the googling around points me to File Alteration Monitor (FAM) as the root cause of such an error.Anyone with an idea on how I may sort this with relation to FAM or something else? I'm still confused about why I get FAM related problems through physical (or at least) network connectivity changes like changing switch ports?

The problem is not yet solved,kindly assist.

I am getting the same error. Squirrelmail has been running for years with on problem and I have not made any changes recently. There will be periods when the issue goes away but then comes back again with no changes from me.


error, squirrelmail
