Apple Mail sending mail from wrong account
One of my biggest bugbears with Apple Mail is that it can send messages from the wrong account (SMTP server) if the first one is unavailable. I can’t avoid this, I can’t prevent it, and it can be very embarrassing or annoying. I run various websites and I like to keep all inboxes totally separate.
So if I get an email to me@domain1.com asking for support, I do NOT want the customer getting an email back from me@domain2.com! But this can happen (albeit rarely, but once is too often)
This can happen due to Apple Mail automatically selecting any other account's SMTP server (seemingly at random!) when the first SMTP server fails which they sometimes do for whatever reason. I need to make SURE this can’t happen.
I have tried doing the usual - selecting the SMTP server for each account, I select the correct one of course and always have. But sometimes for whatever reason that SMTP server may fail, and Mail has a very nasty habit of just picking another one and sending it from there!
I must stop this happening, so I am now faced with paying for Postbox or using Thunderbird to prevent this, neither option I am very happy with but I must stop this happening. Does anyone know how to LOCK Mail down so that, in the rare event that an accout's SMTP server connection fails, the email will just not send rather than just find any other route through my various accounts and embarass me?!
Thanks
