for the smartracksolutions.com site created under ISPConfig2 web interface system, creat a User & Mail as below
Email Address: email@example.com
login into squirrelmail with the login info of the above user & mail, sent an email from squirrlemail to my personal email firstname.lastname@example.org
. in my email@example.com
inbox, the received email is sent from firstname.lastname@example.org
. but it is unsuccessful when reply from email@example.com
the /etc/hostname has only one line "ispconfig.smartracksolutions.info".
why there are 2 email addresses created (but with different domains - smartracksolutions.com and smartracksolutions.info) for one user & mail? how to solve the problem?
