If it were a configuration issue, it would never go through (unless it was a resource that was near its margin). So that’s why I wanted to insert a delay. It appears to me that the segfault is being caused by the file getting moved, deleted, or still being open when sendmail attempts to access it.

I have since changed to using ssmtp (rather than nullmailer as my mail server requires a login, TLS on tcp/587). One thing I noticed, and it may be me that caused it, but the sendemail.py script had some indentation using (4) spaces and some using tabs. But the main problem is that the script keeps warning about the MimeWriter class being deprecated and has no error reporting or recovery, it seems. For me, it was easier to install ssmtp than rewrite the python script. If you don't need a full mail server, I would recommend using a null mailer like ssmtp or nullmailer.<br><br>John<br><br>On 26/01/12 15:13, Rob Morin wrote: <o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>I tried to modify the eximcompat.sh script to work with sendmail.
