Empty messages
 
I have been receiving emails that are empty. No subject or sender and date for these messages is 1.1.1970.
As I was testing I noticed that mail works fine for example from my hotmail account. And from another usual mail account.
But when I send email from my work it comes thru but it is empty.
What system logs should I check because of this ?
Any other suggestions ?

Watch the maillog
 
you'll need shell application like putty if you don't already have it. Then, I would tail -f /var/log/maillog this will allow you to watch postfix in realtime. ctrl+c will stop the tail so you can note any problems. Hope that helps.

mail.log entries
 
Testing again and this is the result:

Aug 15 09:37:24 jailhouse postfix/local[10544]: 1B20C3F1D3B: to=<admispconfig@localhost>, relay=local, delay=0, status=sent (delivered to command: /usr/bin/procmail -f-)
Aug 15 09:37:24 jailhouse postfix/local[10544]: 3FAD23F1D3B: to=<admispconfig@localhost>, relay=local, delay=0, status=sent (delivered to command: /usr/bin/procmail -f-)
Aug 15 09:37:27 jailhouse postfix/local[10523]: F08F83F1D39: to=<user@server.domain>, orig_to=<user@domain.org>, relay=local, delay=4, status=sent (delivered to command: /usr/bin/procmail -f-)

And during this answer came another mail and it was ok.
Hey, I noticed that if I send email from my work in html-format it is empty and if it is text it comes thru ok !!
Does this have something to do with this php error which I noticed too before ? http://www.howtoforge.com/forums/showthread.php?t=236

apache2 error.log:

Have you enabled mailscan or antivirus for this mailaccount, if so try to disable it.

Working ...
 
Yes, that was the problem. Disabling mailscan and antivirus helped.
What shall I do to enable those again ?

I recommend you to enable antivirus again.

Mailscan cleans email messages from potentially dangerous HTML code, javascript and renames attachments with are potential dangerous (e.g. attachment.exe to attachemnt.defanged-exe). Maybe your email client at work formats the HTML messages in a way that the mailscan script finds them potentially dangerous.
