From time to time I have to create a new local Pmail user in our Mercury/Pmail network environment. And everytime I do this I get problems with the max. length and special characters of the new username to be accepted by Pmail. The Mercury help file is stating the following in this regard:
Username
The name the user will give to identify himself to Pegasus Mail or Mercury. By default, this is also the user's address. Usernames cannot contain spaces and must be less than 50 characters in length. Usernames should contain only the letters A…Z, the digits 0…9 and the special characters '.' (period) and '_' (underscore).
But Pmail is accepting only usernames which do not exceed 8 characters/digits in length. This is everytime annoying since I have to create now a shorten username (which differs from the planned e-mail address) and additional a new entry in SYNONYM.MER database with the right assigned e-mail address to that shorten username.
