It seems to be impossible to address multiple recipients using CC or BCC fields.
Whenever I try to address them like this in CC oder BCC-field:
[email protected],
[email protected] it seems RoundCube puts them in double brackets like this "<
>" which leads to a "550 unknown user"-error.
I'm using hMailServer and tried only to address people on my server so the error message might vary a bit on an external server.
However it works when I try to address them directly with the "To:"-Field.
I.e:
To: [email protected], [email protected]
would work flawless while
BCC: [email protected], [email protected]
would not work at all.
I recognized this behaviour also with version 0.2 of roundcube but thought it would have been fixed. Maybe this problem occurs only in conjunction with hMailServer?!
The Roundcube Errorlog shows the following error:
[24-Nov-2009 10:02:56] PHP Warning: mail() [function.mail]: SMTP server response: 550 Unknown user in D:\Inetpub\wwwroot\mail\program\steps\mail\func.inc on line 1389
My E-Mailserver log:

I don't see this with hMailServer. Do you use php mail function to relay the messages or did you configure RoundCube to connect directly to hMailServer by SMTP ($rcmail_config['smtp_server'] etc.)?
I'm using PHPmail for sending, will try to use SMTP - wait.
[Update] Is does only occur when using PHPs mail function - weird. Using SMTP it works fine.
PHP mail is buggy on windows.
