PROXMOX MAIL GATEWAY ADMINISTRATION GUIDE - RELEASE 7.0 - Port list seems incorrect

No, this is correct. Why do you think this is wrong?
 
Yes you are right. I am working my way through the manual from start to end and had not yet read the part about the default part being port 26. Sorry for the confusion on my part.

Maybe you should read to the end first and cry then? I guess, if there are errors or mistakes in the docs, community likes to hear that.... ;-)
