Hello, I am attempting to set up sub-addressing on my Courier mail server, allowing senders to directly deliver messages to a particular folder in my mailbox. For example, I want to provide my University with the address `ash-AcademicMatters@suugaku.co.uk` to force all their messages into the "AcademicMatters" subdirectory. Unfortunately, I can't find any official Courier documentation regarding sub-addressing. I have found [1], however I'm not sure it will apply as I am using virtual mailboxes. When attempting to send e-mail to myself using sub-addressing, my server complains that the address is not found in the virtual users table, suggesting that it is entirely unaware of the sub-addressing notation. Has anyone here managed to get this working ? I believe it is sometimes referred to as "plus-addressing", however it seems that Courier uses a hyphen as opposed to a plus symbol (+). Cheers, Ashley.
