Unable to send mail

[jakobbg]

Have this imap login: jakob@grimstveit.no (yes, I have
to use domain also). When sending to my ISPs smtp
server (smartmail.hjemme.no), it says

SMTP Error in
/files1/www/docs/grimstveit.no/webmail/program/steps/mail/sendmail.inc
(179): Connection failed: 553 5.1.3 ... Invalid route
address

Using latest snapshot.

Perhaps this is related to bug # 1292199 -- RoundCube
appears to mangle email addresses initially for users that
login with the full address. 

Check in your settings and see if your proper email address
is displayed in the identity.

Are you using the php() routine to send mail, or did you 
specified an extra smtp-server in main.inc.php?

Answer to doctormord:

[jakobbg@corona config]$ grep smtp main.inc.php 
$rcmail_config['smtp_server'] = 'smartmail.hjemme.no';
$rcmail_config['smtp_user'] = '';
$rcmail_config['smtp_pass'] = '';
$rcmail_config['smtp_log'] = TRUE;

Yes, there are problems with the SMTP script. This is
subject to be replaced by the PEAR::Net_SMTP package which
is well tested and will surly work better.

Completely new script for sending mail through SMTP.
Should fix this problem.
