SMTP-auth via mailx results in service unavailable

Question

SMTP-auth via mailx results in service unavailable

Why do my attempts to use mailx with Gandi SMTP fail with 'Service unavailable'?

I have the following ~/.mailrc file which is recognised by mailx:

set smtp=smtps://mail.gandi.net:465

set smtp-auth=login

set smtp-auth-user=harry@XXXXXXX

set smtp-auth-password=XXXXXXX

set from=harry@XXXXXXX

set ssl-verify=ignore

set nss-config-dir=/Users/neville/Thunderbird

The result is below.

Whatever client host you're sending from was (is) blacklisted, and this sequence is clearly treated as a relay and Gandi is obviously blocking those.

FWIW, I'd also suggest using ESMTP on TCP 587. TCP 465 and SMTPS are commonly considered deprecated.

See if this SO thread helps you.

http://www.spamhaus.org says:

Mail servers only run spam filters such as Spamhaus PBL on port 25, so if you find you are being blocked by the PBL when you try to send mail to your mail server that means you are not communicating with the mail server on the 'authenticated' port 587 but you're still on port 25. This means your 'SMTP Authentication' is not working correctly.

http://wiki.gandi.net/en/mail/standard-settings#smtp-account says:

SMTP Account

Name server : mail.gandi.net

Port : 25, 465 (with SSL) or 587 (try one or the other)

TLS or SSL: yes

SMTP Authentication : yes, using the same settings as for the POP / IMAP account

I was trying to use the same settings I have used for several years with Thunderbird and Apple Mail, ie SSL on port 465.

Is there something wrong with my settings which could be preventing mailx from using port 465?

A few debug tips would be appreciated.

Your link causes me to ask: Does the mailx on Leopard support SMTP directly?
