[rt-users] RT intermittently fails to send mails after recent Debian Update

Wed Aug 1 10:19:48 EDT 2012

Hi,

I have made a few more experiments here:

First, I tried to forward a failed message. It failed again, but differently. rt.log says:

[Wed Aug  1 14:05:40 2012] [error]: : `/usr/sbin/sendmail -oi -t` exited with code 75 (/usr/share/request-tracker4/lib/RT/Interface/Email.pm:465)

Postfix says at the same time:

Aug  1 16:05:40 jetws003 postfix/sendmail[1741]: fatal: www-data(33): internal protocol error

However, this is not reproducible with other failed messages.

I am starting to believe that I have two different errors here.

What I can reproduce, is a mail triggered by an CGI script which fails all the time.

The CGI Script looks like this: http://pastebin.com/qX0SCkW8

When called with testdata, it creates the ticket, returns OK but the mail doesn't get sent, again with the No Recipient error message of Postfix. According to the logs, the mail did have an receiver:

However, forwarding that message to me does work.

Please note, that both RTs configuration and the code of that CGI script has been unchanged for weeks (perhaps even months) now and it did work last week before the update.
