Hello,
IMAP/SMTP usernames on my server are in form user_domain.tld. When this user first time log in to RoundCube, new identy for him is created with default e-mail adress in form user_domain.tld@localhost, which is unfortunately not accepted by SMTP server (because this user does not exist). So my question is, if there is any way to change this behavior (just pick IMAP username and substitute _ by @).
Thank you very much for your help.
