[OT] sendmail relay to gmail smtp server
First let me say, I'm not interested in switching mta's.
I want to use gmails' smtp server as Smart Host for my single user
debian box running sendmail-8.14.4
I'm hooked up to an ISP called direcpath.tv in Atlanta that uses gmail
smtp servers for its clients with addresses like reader@direcpath.tv
They have terrible to non-existent support and no support of linux/sendmail
They use smtp.gmail.com But before I get into the extra complication
of their direcpath.tv overlay, and since I do have a normal gmail
account I thought I'd first try to get the authentication for smtp
working for that username. hputnam3@gmail.com
So after dozens of small edits and restarts and makemaps ... cutting
to the chase:
/etc/mail/authinfo
(password obfuscated)
,----
| Athinfo:smtp.gmail.com "U:root" "I:hputnam3@gmail.com" "P:??XX??" "M: LOGIN PLAIN"
| Athinfo:smtp.gmail.com:587 "U:root" "I:hputnam3@gmail.com" "P:??XX??" "M: LOGIN PLAIN"
`----
------- --------- ---=--- --------- --------
And I think what are the most relevant sendmail.mc settings (the whole
*mc is inlined at the end).
/etc/mail/sendmail.mc
,----
| define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
| define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
|
| FEATURE(`authinfo', `hash /etc/mail/authinfo')dnl
|
| define(`confAUTH_MECHANISMS',`EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
| TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
|
| define(`SMART_HOST',`smtp.gmail.com')dnl
`----
(And for the record, I did try bracketing the Smart Host like:
define(`SMART_HOST',`[smtp.gmail.com]')dnl)
I have some old masquerade settings that I doubt are causing a
problem. I do have an account with them too. I think the error would
be different if they were causing problems, but here those are:
(Note, that removing those only gets the same error messages)

The `learn more' address give just above is not all that helpfull.

I think these are the sendmail logs that contain the relevant error:
(I'm not sure if the `verify=FAIL' means what it suggests)
