Paul,
Yep. That's what I mean. I'm still learning the language and the tools.
All this to avoid being greylisted when I send mail to domains that check
for authentication.
If so, then something like this works:
smtp-server=mail.appl-ecosys.com:587/user=rshepard/tls
Where does this go? I'm not forwarding mail through another mail server so
the port should be 25 ... I think. I believe that I need to also set a TXT
record on my DNS server for SPF and, perhaps, one for DMARC. Much to learn
and looking for resources.
The hostname, port, and security protocols may need adjusting, depending
on your setup. (If your mail server isn't listening on port 587, you may
want to look it up.) If you're using straight SSL, that directive might
look like this:
smtp-server=mail.appl-ecosys.com:465/user=rshepard/ssl
I don't know what postfix is using here. I have the router set to forward
incoming mail through port 25; outgoing mail uses teh same port. I've not
explicitly set SSL or TSL for alpine/postfix.
This all assumes, of course, that your mail server has already been
configured to handle user authentication...
I've installed opendkim but have not yet started it.
I think we're talking passed one another.
DKIM "authentication" won't involve alpine in any way. Mail might be
rejected at the SMTP level by a DKIM-aware milter, e.g.,
https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-dkim-with-postfix-on-debian-wheezy
Similarly, filtering software like SpamAssassin has network checks for
performing DKIM verification. You then tell SpamAssassin (or its ilk)
how badly to score messages that don't pass verification.
All Alpine does is read the mail delivered to you. It doesn't make any
assessments about the worthiness of those messages.
