Aliases are one of the most powerful pieces of Smartermail, in my opinion, and have helped us sell SM versus other solutions to clients - but, there is one piece that has always annoyed me and the solution/work-around is a real pain in the butt. That is - you can't change the display name of an alias you can send from.

Let me explain with a real example - 

Example Inc has a user bob@example.com and an alias accounting@example.com that goes to bob@example.com. The "Alias can be used as from address in webmail" option is selected. Bob now can send and received as both bob@ and accounting@ easily. However, when sending out as accounting, Bob doesn't want his name to be the display name, he wants it to be "Example Inc Accounting" because he wants the emails to appear to be from the department and not from him personally. He can change his signature automatically based on which alias he is sending from, but the display name is always his.

The work-around we've created is to make accounting@example.com a user, not an alias, and then set it up as an external SMTP account in webmail, but in an environment where we are charged and licensed per user - this is not an ideal solution to solve such a simple thing.
