not receiving mail

[damon]

I setup a new account for someone, and the accounts were not able to send mail. It received mail fine, then after a while the other accounts started being able to send mail. I have no idea what to check for.
I removed the account, and set it up again, using a different login, the login mail will still not send mail. I ran into this problem before, and it fixed when i reinstalled the account...not this time though. Anyoen have any ideas on what i can check?

Two things:

1. run /scripts/mailperm

2. Monitor your mail logs for errors when they try and send:

tail -f /var/log/maillog

I presume that you've checked that they are authenticating before sending either by POPing their account immediately before, or using SMTP AUTH.
