Email was working, not anymore

[andrescrucitti]

I have a few email addresses set up on my cPanel. Everything was working fine at least earlier today, but tonight we realized that emails are not being sent or received, not locally or with outside servers, not through webmail nor php.

I tried restarting the service from whm and looking around on cPanel I didnt notice anything that was changed.

Does anybody have any ideas?

Through php I dont receive any errors. Squirrelmail returns this when i attempt to send an email to either an outside or local address:

Message not sent. Server replied:

Requested action not taken: mailbox unavailable
550 Verification failed for <andresc@dascheap>
The mail server could not deliver mail to andresc@dascheap. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries.
Sender verify failed

Weird thing is that imtrying to send from andresc@dascheap.com, but it says that it cannot DELIVER mail to <andresc@dascheap> ???

What can i do? It was working just this morning... for sure maybe 8-10hrs ago

Checked on WHM back end... on the mail queue there's a bunch of email that havent been delivered... every time I attempt to deliver it i get his error message:

Message 1O4Kmb-0002rs-TV is not frozen
delivering 1O4Kmb-0002rs-TV
LOG: MAIN PANIC
Error in system filter: quote missing at end of string in line 96


how come something like that come out of nowhere? and how can it be fixed?

I have seen this very same problem with a couple servers this week ....

Interesting:

Error in system filter: quote missing at end of string in line 96

Any time mail does anything with the Panic Log, this is a major issue that needs to be investigated. I recommend letting a technical analyst login to your server and diagnose the issue.

If you want to attempt self-diagnosis first, the panic log for Exim (SMTP Mail) is located at:

/var/log/exim_paniclog

If you are on FreeBSD, substitute _ with / in the above path.
