RE: postfix+cyrus errors

I found this in the wiki, question is what is the proper way to escape the
 <at> ??

<--snip-->

Given that you have a username john <at> domain.tld, unless you escape the ' <at> ' as
explained below, cyrus deliver will claim that the mailbox does not exist. 
instead of 
• deliver john <at> domain.tld 
you should be using 
• deliver john\\\ <at> domain.tld 
and 
instead of 
• deliver -a john <at> domain.tld -m user/john <at> domain.tld 
you should be using 
• deliver -a john\ <at> domain.tld -m user/john\\\ <at> domain.tld 

Thanks

Subject: postfix+cyrus errors

I’m trying to setup postfix+cyrus+mysql+web-cyradm+cyrus-sasl. I changed
web-cyradm so when it creates mailbox for domain the account looks like
user <at> domain.com and not user.domain.com. I have that working correctly. I
can also login to the server (pop, imap) using user <at> domain.com and pass just
fine…However, whenever I try to send a mail to that user I get the following
error

<user <at> domain.com>: data format error. Command output: user: Mailbox does
    not exist

2BF632530085: to=<user <at> domain.com>, relay=cyrus, delay=0, status=bounced
(data format error. Command output: user: Mailbox does not exist )

I can login using cyradm and verify there is a mailbox user <at> domain.com, I
also tried creating user.user <at> domain.com but to no avail. Any help would be
GREATLY appreciated.

Thanks
