UNIX for Advanced & Expert Users

Hi All,
I am using svnnotify (which is available on net) script to send svn commit notification.
Everything was working fine up to yesterday but from yesterday i started seeing error.

Code:

29CD01FCE44     7228 Thu Apr  5 11:11:51  apache@vm0001.host.com
(host mail.mailserver.com[10.14.100.54] said: 452 4.3.1 Insufficient system resources (in reply to MAIL FROM command))
[10.14.100.54]:25, delay=75560, delays=75495/55/5/5, dsn=4.3.1, status=deferred (host mail.mailserver.com[10.14.100.54] said: 452 4.3.1 Insufficient system resources (in reply to MAIL FROM command))

I tried various options to solve bug nothing seems to be working.
when i try to send mail to my gmail id it is being delivered but it i tries to send mail to my corp id i am getting above error.


Please help.

I believe your corp server is MS Exchange based. If yes, have you checked with mail server admins if the transport server are running low on disk space/memory, search for "Back Pressure" on exchange server, it might give you some lead.

Please provide more details about your corp server

I checked the guy who manages the corp server but since mails are going fine to my gmail or yahoo id as per my initial mail.
even with in our company mails are flowing through that is why low disk storage or resources are not available are not seems to be true for me.

First check with the unix mailq command to see if the mail is still queued on your server. If it isn't, then this is just a temporary overload on the SMTP email server upstream of your server. The message "Insufficient system resources" usually comes from a Microsoft Windows server which is in need of a reboot or a reconfigure (or both).

Yes, mailq was showing 100s of mails in the queue, apparently send mail started working yesterday afternoon and all messages got delivered. Thought my problem is solved but i am not enjoying it.
I am still not sure what was the problem and how it got fixed, so may be methyl, you are right. Email server was overloaded but still i was wondering why mails were going to gmail or yahoo id but not to corporate it. If server is overloaded then mails shouldn't go at all.

I would be surprised if you had just one mail server in a Corporate environment.
Best guess (without knowing much about your environment) is that the SMTP front-end server was not overloaded and was able to relay mail to your external mail server, but your internal Microsoft Exchange server was overloaded (or hung awaiting reboot) and deferred all internal mail.
It is possible that all these relay servers are one physical computer - in which case I wish you luck.

Since i don't manage the mail server so i have no idea. But you may be right.
I will keep the conversation open with support guy in my company and try to investigate on your suggestion.
