Public bug reported:
Binary package hint: libapache2-mod-php5
My shared webserver suddenly stopped mailing yesterday. Both the PHP
mail() function or calling /usr/sbin/sendmail directly from exec() or
something similar gives this error in /var/log/exim4/mainlog (of course
/usr/sbin/sendmail is just a symlink to exim4):
2009-08-26 13:35:51 1MgGn9-0002rA-Tm == h...@example.com R=smarthost
T=remote_smtp_smarthost defer (-1): smtp transport process returned non-
zero status 0x000b: terminated by signal 11
After a long search I finally found that mailing starts working again when I
delete a few random Apache VirtualHosts. I can really not explain why this
happens, but I can reproduce this behaviour every time. The VirtualHosts
configuration is certainly correct, and Apache nor PHP gives any error message.
The mail is added to the exim4 queue correctly as far as I know, but it is not
sent and frozen immediately. With exim -M message_id on the command line I am
able to send each message afterwards without a problem. I tried different exim4
configurations (without smarthost for example), but that doesn't give any
change.
On another server I use suPHP (CGI), with exactly the same versions of Apache
and Exim4, there this problem does not exist. Also on the server where I have
this problem a Perl CGI script that calls /usr/sbin/sendmail runs just fine,
and sends the mail. So I think it must be some bug in libapache2-mod-php.
