i have a user lets call him firstname.lastname@example.org who is setup with a catchall at this address. so people can email email@example.com or firstname.lastname@example.org and it will go to john's mailbox.
however this morning john experienced an issue where another user on the example.com domain tried to email email@example.com from the account firstname.lastname@example.org but the email ended up in john's mailbox (and no the email was no misspelled.) When john replied to the email from Sarah it went back to her mailbox properly.
anyone else ever experience this issue? I just tested it myself now and it doesn't seem to be happening from my account (on a diff domain, but same server). But I can see from john's mailbox that this definitely happened.
