Hi, not entirerly sure wether this is the right place to ask. Sorry if not. I´m running dovecot on a Mac OS X Server (10.6.4). Everything works fine. When I try to enable a vacation message, I get the following error in the log: delays=0/0.01/0.09/0.1, dsn=5.0.0, status=bounced (host XXX[x.x.x.x] said: 553 Mail to <name@domain.tld> not allowed; missing domain name in MAIL FROM (in reply to RCPT TO command))

Where host is the mail relay. The logs on the mail relay show matching entries. Sending mails is generally working.

I´ve sniffed the network traffic and the FROM Field in the SMTP transfer contains only the following text: <>

I´ve allready set the value of myorigin in /private/etc/postfix/main.cfbut to no avail. Can somebody tell me where I can set the sender address of the vacation mail? Or is there something else wrong?

The <> represents the "null sender" in SMTP parlance. I think the issue here is that the destination SMTP server does NOT accept the null sender (<>), and that is a br0ken configuration. It has nothing to do with Dovecot though. I am not good at interpreting postfix logs so I cannot advise further.
