Did you try the latest svn versions?<br>There were a lot of bugfixes. 
Don&#39;t know about a potential sendmail bug though...<br><br><div class="gmail_quote">On Thu, Jun 24, 2010 at 11:53 AM, Stuart Bailey <span dir="ltr">&lt;<a href="mailto:stuart@linusoft.co.uk">stuart@linusoft.co.uk</a>&gt;</span> wrote:<br>

an internal error.<br>
<br>
I have just upgraded from roundcube-0.3.1 to 0.4-beta. I&#39;m now seeing a problem<br>
sending messages with attachments. On send, there is an error popup that<br>
disappears too quickly to read it. The message does not get saved into the sent<br>
items folder. In the logs, I get:<br>
<br>
[24-Jun-2010 09:44:40 +0100]: IMAP Error: Could not save message in Sent<br>
in /srv/www/htdocs/webmail/program/steps/mail/sendmail.inc on line 620<br>
(POST /webmail/?_task=mail&amp;_action=send).<br>
<br>
Any suggestions would be appreciated<br>
<br>
Many thanks<br>
<br>
