Re: [rt-users] Postfix sendmail returning status code 75
My guess is that you're running RT 4 under mod_perl with the wrong SetHandler value. Read http://bestpractical.com/docs/rt/latest/web_deployment.html#mod_perl-2.xx and compare your config. No, mine seems to check out. Here it is: AddDefaultCharset UTF-8 PerlSetEnv RT_SITE_CONFIG /etc/request-tracker/RT_SiteConfig.pm # You might need to alter references to /rt in this file (there are # three) to match whatever base URL you are using for your RT site Alias / /usr/share/request-tracker/html Location / SetHandler modperl PerlResponseHandler Plack::Handler::Apache2 PerlSetVar psgi_app /usr/sbin/rt-server # Options None # Order allow,deny # Allow from all /Location # Limit mail gateway access to localhost by default Location /REST/1.0/NoAuth Order Allow,Deny Allow from 127.0.0.1 /Location Perl use Plack::Handler::Apache2; Plack::Handler::Apache2-preload(/usr/sbin/rt-server); /Perl Today I have been keeping a close watch on the server's memory. So far I haven't seen any less than 80% free, and no error so far, either. Nathan
[rt-users] Postfix sendmail returning status code 75
I'm having a devil of a time with this. We're running RT 4.0.13 on SUSE Linux Enterprise Server 11 SP2. The MTA is Postfix. Seemingly for no reason, outgoing emails from RT start failing. Cleaning the Mason cache and restarting Apache2 seems to solve the problem temporarily (some hours, but by the next morning at the latest the problem returns). Each time it drops an email in this way, RT writes the following two log messages: RT: rt-4.0.13-7424-1375250475-1273.35071-...@suse.de: `/usr/sbin/sendmail -oi -t` exited with code 75 (/usr/lib/perl5/vendor_perl/5.10.0/RT/Interface/Email.pm:486) RT: rt-4.0.13-7424-1375250475-1273.35071-...@suse.de: Could not send mail with command `/usr/sbin/sendmail -oi -t`: rt-4.0.13-7424-1375250475-1273.35071-...@suse.de: `/usr/sbin/sendmail -oi -t` exited with code 75 at /usr/lib /perl5/vendor_perl/5.10.0/RT/Interface/Email.pm line 487.

If I don't restart Apache, the problem seems to get worse over time. I have prepared a wrapper for sendmail that will log the exact messages that are causing this to happen, but I haven't deployed it yet. (Still testing it.) Since status code 75 is only a temporary error whereby Postfix is (apparently) just saying that it is queuing the message to send later, I'm wondering if I could just patch RT to ignore status code 75 and treat it the same as success? Any other ideas? Nathan

Re: [rt-users] Postfix sendmail returning status code 75
Thanks for your reply, Kevin, and here are my answers to your questions. What kind of monitoring do you have on the box? Often, this is a memory problem (the running out kind). We are monitoring the box with Icinga. I will talk with my colleagues to see if we can tweak the Icinga configuration so it complains earlier when memory starts to get low. The box has 8Gb installed, but it runs more stuff than just RT. PerlOptions +Parent was required because they ran two perl processes in a single mod_perl host. Are you doing that? Well, I'm certainly not. And it didn't make the problem go away, so I assume this is a dead end and I will remove that option. What's in your postfix error logs when this happens? postfix/sendmail[26576]: fatal: wwwrun(30): No recipient addresses found in message header My sendmail wrapper is now in place and I will be watching closely tomorrow. Today from what I managed to capture it looked like nothing (or only one byte?) was being piped from RT to sendmailpipe. This is consistent with what was written to the log (No recipient addresses found). Thanks!
