I have 2 major problems with RC2:
1.) Mails being sent are from "postmaster@mydomain.com", and not from the real sender Email Address, which causes non-delivery notifications (in case the receipient is wrong) being sent back to "postmaster@mydomain.com".
Here my mailserver log:
"SMTPC" 2588 82511 "2008-01-02 10:06:49.734" "149.148.224.15" "SENT: MAIL FROM:<postmaster@mydomain.com>"
2.) If I am using the address directory of a receiver with a friendly name e.g. "John Doe" then squirrelmails addresses the receiver in the SMTP session incorrectly. Here an excerpt of my Mailserver log:
"SMTPC" 2588 82511 "2008-01-02 10:06:49.734" "149.148.224.15" "SENT: RCPT TO:"
"SMTPC" 2588 82511 "2008-01-02 10:06:49.734" "149.148.224.15" "RECEIVED: 501 5.1.3 Bad recipient address syntax"
The first line is incorrectly formatted and will be rejected by SMTP servers.
It should look like this:
"SMTPC" 2588 82511 "2008-01-02 10:06:49.734" "149.148.224.15" "SENT: RCPT TO:"
This makes Roundcube pretty much unusable. I am reverting back to Squirrelmail, until those 2 issues have been fixed.
