Critical Bug Plesk 10.3 Centos 5.6 and Postfix

    Just with pure luck we found a critical bug which is causing email to vanish.

    If an email user is created and you use uppercase letters in Plesk, postfix will not be able to route incoming emails because postfix assumes lowercase emailnames instead of lower/uppercase.

    Problem is that this email will simply be dropped so the sender as well as the recipient don't notice.

    Luckily we found this critical bug today after 2 days running Centos 5.6, Plesk 10.3 and Postfix. All up2date.

    Would be great to have this fixed as right now I can use the telephone and call the customers to be careful when creating an email user but I will forget this in a couple of weeks.

    It is well known serious problem which couldn't be decided in this request. Because it touches a lot of places into BL, backend and API. Will be fixed in a future releases.

    As workaround you should not use mixed case e-mail addresses at all. And rename mailbox to lowercase.

    Thanks a lot Igor for taking the time to report back and to honestly gave this info.
    Like I wrote I talked to the customer who have the rights to manage there own subscription so lucky enough the error was found very fast. The problem with an error like this is that you can't imagine how much people trust emails with orders and offers, even if it's worth of thousands of euros and not ask back to make sure the recipient has received the email.

    Sorry but we haven't so many resources to make the full internal redesign of Plesk and release it during such short time.
