[SOLVED] Need Help: SMTP Authentication and Port Modification

[mconder]

I am trying to authenticate to DynDNS's mailhop server, but I am getting the following in my zimbra.log:

zimbra@ubuntu-srv:~/conf$ grep -i mailhop /var/log/zimbra.log
Oct 16 16:08:06 ubuntu-srv postfix/smtp[13875]: 6B958633D: to=, relay=outbound.mailhop.org[63.208.196.178]:2525, delay=1.1, delays=0.15/0.21/0.64/0.07, dsn=5.0.0, status=bounced (host outbound.mailhop.org[63.208.196.178] said: 550 You must authenticate to use MailHop Outbound (in reply to MAIL FROM command))

I have been trying to configure Zimbra for SMTP authentication all day. Here is my postfix mail.cf

sender_canonical_maps = proxy:ldap:/opt/zimbra/conf/ldap-scm.cf
virtual_alias_domains = proxy:ldap:/opt/zimbra/conf/ldap-vad.cf

smtp_tls_CAfile = /opt/zimbra/postfix/cert.pem

Here is output for postmap -q ubuntu-srv.appconnex.com /opt/zimbra/conf/relay_password:

So what am I doing wrong here?

Thanks!

If there is anyone who knows how to get SMTP authentication working, PM me and I'll give you login to my server. It's just a test server, so I don't really care if it gets screwed up. I have a VMWare snapshot anyway. I just want to get this working. Please help!

I have not tried using DynDNS SMTP, so I can't comment intelligently about your set-up, but this wiki might be helpful to you.

[SOLVED] multiple accounts on smtp relay

I think the user may have been dealing with similar issues to those you encountered already or will encounter. This thread illustrates both what you can and cannot expect from externally-authenticated SMTP.
