I think Bill was just trying to let us know why auto-deletion is thought 
of as a very good thing if you are a server administrator. Never/rarely 
permanently deleting the emails in Deleted Messages is something I'm 
guilty of myself, but I am also the server administrator of my email 
accounts :)

I think the feature you are looking for is “Mailbox ▸ Mailbox 
Type”. Create a mailbox for deleted messages, for example, named 
“Deleted Messages” within the Gmail account and then use “Mailbox 
▸ Mailbox Type” to make MailMate use it when you delete messages. 
This way Gmail won't auto-delete the emails since this only happens for 
“[Gmail]/Trash”. Gmail just considers “Deleted Messages” mailbox 
to be just like any other mailbox (or “label” as Google likes to 
name them).

Note that a side effect is that MailMate won't any longer consider 
“[Gmail]/Trash” to be a mailbox with deleted messages. Any emails in 
that mailbox are going to be part of, e.g., “All Messages”.

I hope that helps.
