Huh, who said anything about gmail?You can set up gmail to reply from one specific account regardless of which one you use. I would suggest going that route.
Just go to the gmail page on your computer select settings and then accounts. You can then select which address to reply from.
IF you've figured out a way for GMail to respect default account settings via POP, please share... I can only reply as my @gmail.com username... not as my domain which I pass through gmail server. It's impossible to reply to lists that are subscribed on another account...Maybe I wasn't clear. i was suggesting gmail as an alternative.
In my experience you can can only reply the account to which something has been sent. Not sure what default account does as it's a total number of new messages from all accounts in the unread icon on the home screen. When you create a new message, it will be from the account you are in as well - not your default.This doesn't make sense, I've NEVER seen a mail program act like this. If a message comes in from pop or imap and I reply to that message the mail should be FROM that account, not a default account. If there is no way to send the message from who it was too this is a MAJOR design flaw.
