[ubuntu] Problem with Postfix Mail Server 2.7.0

[Rackenford]

I know very little about Linux.

I have recently started at a school that has a Linux server which manages external mail coming in.

I have a Webmin console that I have login details for and i can see a mail queue of external mail building up. This happened 1 week ago and i rebooted the Linux server and they all delivered. Now it has happened again and the reboot has done nothing.

 

If i click on the Mail Queue i am informed (lots of times):

host xx.xxx.xx.x said: 452 4.3.1 Insufficient System resources (in reply to MAIL FROM command)

 

If i click on the System Logs and look in the mail.err log, i have (lots of times):

SVR04 MailScanner[XXXXX]: File checker failed with real error: Insecure dependency in exec while running with -T switch at /usr/share/MailScanner/ /MailScanner/SweepOther.pm line 374

 

That is my extent of Linux. If anyone could offer any guidance, i would be eternally grateful as i have no external email coming in.

 

Look forward to hearing from anyone.

Do you know what version of MailScanner you're using on the linux box?

 

Looks like you're running out of resources for Postfix to do its thing because MailScanner is locking up dealing with attachments, they say this specific error "insecure dependency ..." is fixed in newer MailScanners than 2009.

What i can tell you:

Ubuntu Linux 10.04.3

Webmin version 1.530T

This MailScanner browser was written by Richard Lush

Version 1.1-4 BETA

2nd February 2005

 

If this is not what you are after, please advise. Thanks

Rebooted Exchange Server and mail is flowing again but, no idea what the problem is so would be nice to sort.

Just to pop up a new note but, i am still have no resolution to this. Restarting the Exchange Server every 3-4 days is sorting it but.................
