Hello, we have a few clients that would like to use our smtp server for sending email. How would i set up a user in ISPCONFIG to do this. Only for sending email not receiving? Keep in mind there might several emails of the same domain. Thanks...
Create a mailbox in ispconfig, name it e.g. "smtpout.customerdomain.tld" or something similar that does not collide with names of incoming email accounts, disable receiving for that mailbox. Additionally, you will have to allow sending with different mail addresses under System > Server config > mail.
