one of my users can't recieve email from one of his friends. his friend's
email is getting bounce back, with the message:
571 sorry, sender address has invalid format (#5.7.1 - chkuser)
is the friend's email not configured right? from what i've researched,
this may be the case. two questions:
1. can i disable this chkuser function so the friends email will go through?
2. is this something that i would want to do, or would there be
undesirable results?
thanks!
I don't think you want to disable chkuser entirely. It does some nice
things to fight spam.
Look in /var/log/qmail/smtp/current (or @40*.s) for message(s) from
chkuser (grep CHKUSER /var/log/qmail/smtp/current). You might also
simply grep for 'rejected'. Take a close look at the rejected log
message, which will show the "envelope's" (as opposed to the
"message's") sending address. Are there any special characters, like '$'
or '^' or '~'? They would cause a rejection.
If that's your problem, check the email archives for subject "CHKUSER
rejected..." and reply from Nick. He explained the easiest way to change
your chkuser settings. You'll want to add whatever special character(s)
you need to the chkuser_settings.h file.
If that's not your problem, please post the log's rejected message.
