Benny is (of course) correct, Dave, but you could set up a message 
verification (as described at 
https://manual.mailmate-app.com/hidden_preferences) and have it trigger 
for all messages. Of course, it won't help if you develop the habit of 
automatically clicking OK to the alert, but it can at least pop up an 
alert to remind you to check the address you're sending from.

Or you could create more targeted verification checks that trigger only 
under certain conditions, when you're clearly sending from the wrong 
account. For simple cases you can just list the explicit conditions in 
the messageVerifications.plist file (if "TO=boss" and 
"FROM=wizard-elf-lord-of-Saurons-kittens" then warn "Yikes!"), but for 
checks involving groups of addresses ("never use email account A to 
write to anyone in group X"; "never use email account B to write to 
anyone who isn't in group Y") you may want to check out a long email 
thread on this mailing list under the subject line "check whether a 
recipient is in a certain group?" I started it as I worked out (with 
Benny's invaluable help) how to do just that, and the method he helped 
me develop has saved my bacon several times. (To summarize, though this 
may look like gibberish until you're read the manual on hidden 
preferences: The condition

"(from ~[c] 'problematic.address at example.com' and #recipient.address 
!=[c] 
$'imap://problematic.address@imap.example.com/list-of-addresses'.#recipient.address)"

triggers when a message is about to be sent from 
"problematic.address at example.com" to any address that is not in the TO 
line of a dummy draft message in an IMAP folder titled 
"list-of-addresses" in the problematic.address account. Keeping a list 
of approved addresses in that dummy draft message thus ensures that I 
will never accidentally write to anyone from that problematic.address 
who isn't on the approved list to receive email from it.)
