[MlMt] Wrong SMTP

[David Wainberg]

Hi all,

I can't figure this out, and hope someone can help. Maybe I'm just doing 
something dumb, but I can't see it. I'm using Version 2.0 (6203).

It appears to me that MailMate is using the wrong SMTP server when I try 
to send using an arbitrary email on my domain, as Fastmail allows.

FastMail allows creating a catchall address, which then allows sending 
and receiving using arbitrary usernames, i.e. <whatever>@domain.com.

When I send from my regular email address on this account, i.e. my 
username for the account, it sends fine.

However, when I send using one of these catchall addresses in the From 
field, it appears, from looking at the Activity Viewer, that MailMate 
switches to using the SMTP settings for a different account/domain, 
rather than the account/domain that I'm sending from. So, I get a "Not 
authorised to send from this header address" error.

Any idea what's going on?

Regards,

David
