Re: [Evolution] SMTP Question




For a couple of accounts that I have (paid EMail accounts) it seems
that I need to pay for SMTP Authentication to send mails from a
client.

I would very much doubt you need to pay twice - once for receiving and
once for sending...

 The first question is:
Do I need multiple SMTP connections? IE Can I send a mail message from
say blah somemail com via an SMTP connection at smtp.blah.blah. Can I
just use one smtp account to send all my mail, even though the 'From'
is not part of that 'email domain'?

That's called open mail relaying and virtually all SMTP servers will
block it - it's the way that much spam used to be sent.  i.e. if you can
use an SMTP host to send mail to any domain without authenticating
first, then so can Mr Spammer.  In fact it doesn't matter what your
From: header says (since Mr Spammer can also easily fake that), you
should only be able to send mail to external domains if you are
authenticated.

BTW, from experience, what happens if you accidentally leave a mail
relay open and a spammer finds it is that your server will suddenly be
abused by a couple of million messages being blasted at it; and very
quickly all the blacklists will have the server listed and you won't be
able to send legitimate mail out and it will take you months to recover!

 Where is this smtp server detail coming from? Is there another config
file I need to change?

It's only in the account configuration page - and it's all done on a
per-account basis - so make sure you are sending your email from the
correct account.
