Improving mail accounts

[joximu]

ok, smtpauth with a different user is possible but if you have some sort of business customers then you may understand that it can happen that they don't want to tell others their mail password or they don't want to create an account just for sending... so this is a second motivation for the password...

forward vs alias - there are some slightly differences:
- forwardings are one to one-or-more, aliases are only another one to the same account.
- aliases are handled more easily (just add some other names in your mail account) by the customer, you don't need a virtual-mail folder for the address etc etc.
- the autoresponder maybe implemented differently with aliases (no problem: all addresses are automatically responded) than with forwardings (the autoreply needs to do severall db queries to get the target address and see what message it has set - or forwarding addresses just are not responded at all...). - I see some advantages with this two possibilities. Even if postfix handles them the same way: with aliases the domain-internal address handling may be simplified.
- a forwarding address may have a password (also to change the target address) - an alias address does not need anything.

... not a very clear report but some thoughts that come together... :-)
