[Mailman-Users] Strange error with Mailman 2.1.9

[Richard Hartmann]

Hi all,

I have this in my error log:

And my in looks like:

Things I checked are:

1) free disk space: more than enough
2) free inodes: more than enough
3) no SELinux or other security/restriction framework installed
4) bin/check_perms does not list any errors
5) other email is delivered


Any other ideas what to check? Upgrading Mailmain is an option, but I
would like to avoid that, if possible.


Thanks for all feedback,
Richard
