We are running Mercury as well, is this the gateway you mention?
Yes
I have looked at PMAIL.CFG and it has the following text
" \server\mail\box~8 \server\mail\box~8 "
These appear to be invalid paths but since they must be valid if the clients can access mailboxes.
Not sure what the ~8 is doing, there are only 4 folders (with names of the users plus a folder called General where all old mails are stored) and a PMAIL.USR file in "box"
The "~8" is a placeholder for the current Pegasus Mail username (up to 8 characters). This is how Pegasus Mail and Mercury know which mailbox directory to be working with.
So do you think its Mercury that's the problem?
Mercury can't send a message that doesn't get submitted to its queue and I suspect your point of failure is queue submission although identifying why the host is working but the clients aren't could shed some light.
If you want to create a new PMAIL.CFG file, backup your current one and then, with Pegasus Mail closed on all machines, run pconfig32.exe on the host. Pconfig32 is pretty self-explanatory and has a "Mercury" button that is supposed to ease gateway setup process when Mercury is the gateway (I have never used it). Note: When entering the path to the root mailbox directory you will need to add "~8" at the end. Based on what you have posted I believe that path should be \server\mail\box~8. Be certain that the clients can navigate to this path. Use a file explorer on the clients and manually enter the path, without the "~8", to make sure they can access it. The same goes for the path to the Mercury queue directory.
You may need to start a new post on the Mercury forum if more discussion about Mercury is required.
