On Dec 24 2009 13:47:32 I got the following error in my majordomo.log

WARNING  Failed to open temp file '/usr/tmp/resend.5590.out', it exists
ABORT resend: Can't open /usr/tmp/resend.5590.out: Illegal seek

I checked the resend.5590.out file in /usr/tmp and can see that it was
created in Dec  1 2009 22:16 and also realized that there is a
resend.5590.in file present.

I dont really know the meaning or causes of the error.
and would be glad if someone could explain it to me

Also the difference between resend.xxx.out and resend.xxx.in files and
the reason why they are created.

Info about the majordomo I'm using
majordomo-1.94.5
perl v5.8.5
Linux (Redhat)
Qmail

I am new to majordomo and would be glad to have some information on this matter.
Thanks in advance
