HI, 

I've some issues with recieving mail recieved through POSTFIX. I 'm running a ticket system, on a turnkey LAMP appliance.

Mails sendt to our support mailbox is recieved by POSTFIX and is normally delived to the ticket system through a PIPE. Mails are then parsed by the ticket system.

The problem is That som emails (around 5% - Isch) is bounced to sender with a NDR.

each of theese bounced mails can be found in mail.warn log

postfix/local[1538]: warning: pipe_command_read: read time limit exceeded

I cant figure out why this issue occours. I Cant trigger the issue by a single mail. The ticket system is parsing the mails in 0,1-2,5 sec.

Then the issue occours, the mail is placed in the mail que, I can re-schedule the mail, and its delived just fine...

I need any hint that could lead me info a fix.
