Hi,
I'm using roundcube (v 1.4.3) with Ispconfig.
I've my own domain (example.com) with multiple mailbox (barbara@example.com, etc).
As my new ISP blocks SMTP Port 25, I edited the roundcube config file to have the gmail smtp settings ($config['smtp_server'] = 'ssl://smtp.gmail.com'; $config['smtp_user'] = 'xxxxxx@gmail.com'; etc.).
It works both with tls/port 587 and ss/465.
The odd thing is that the "smtp_user" becomes the sender identity, so if I send an email as barbara@example.com, the recipient of the mail will see xxxxxx@gmail.com (and not barbara@example.com) as sender -- that only happens with gmail smtp settings.
(btw, If I use another server as smtp, the sender remain the original, but then gmail doesn't accept the mail).
I hope I made myself clear,
any suggestion will be welcome, thank you!
