mail for one user suddenly stopped with postfix
I'm using Postfix, Amavisd with spamassassin, and Squirrelmail. Using IMAP and maildir.
Just noticed that over the weekend one user stopped getting mail. Nothing even in the queue for them newer that sometime yesterday. This morning, no email. I however was still getting mail, not sure about others (we aren't a very big place). I went in via webmin, saw nothing in the queue new. SSHed to mail server, and sent a message manually to the user (I tried to send them one from my client to them, it didn't show up in the queue.) The cli sent message went through. then another email sent from my client program went. sent from gmail to this server, it got that. Now other emails are coming in for this user.
Gonna look at logs as soon as I can, but this is way wierd so far. Why did sending a message via the cli "restart" mail for this user????
