dovecot - Aug 2010 - sender address of sieve vacation script

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 at 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.cf but to no avail.
Can somebody tell me where I can set the sender address of the  
vacation mail?
Or is there something else wrong?

Thank you very much.
Best regards
Wolfgang

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.

100% correct answer.
I checked with the admin of the relay and it?s working now.
Thank you very much
