Issues connecting to smtp server from postfix client
Vic
understand what I'm missing, so I turn to you guys for help... My
smtp server is NOT internal, and I do not manage it. All I know is
that it is NOT asking for a SSL or TLS handshake:
# gnutls-cli-debug -p 587 MYRELAYHOST
Resolving 'MYRELAYHOST'...
Connecting to 'MYRELAYHOSTIP:587'...
Checking for TLS 1.1 support... no
Checking fallback from TLS 1.1 to... failed
Checking for TLS 1.0 support... no
Checking for SSL 3.0 support... no
Server does not support none of SSL 3.0, TLS 1.0 and TLS 1.1
Here are the relevant files:

I also do have the /etc/postfix/sasl_passwd postmapped. Here is my

Any help would be appreciated, I'm at a loss right now and don't know
what to try next (I've done postfix, postfix with SASL, postfix with
SASL and TLS). What I don't want to do is to set up my own mail
server, as there is no point, I pay for service from the MTA I'm
trying to connect to.

I have the same issue. I have a Linux server with Postfix Client
trying to send email via smtp service in Exchange 2007 server. I'm
able to send email using "telnet smtp.server.com 25" using "AUTH
LOGIN" credentials. But I consistently get "5.7.1 Client was not
authenticated" when sending mail using "mail -s Test j...@x.com".
Did you solve your problem?

I found the solution to my problem. It appears postfix kept applying
the PIX workaround which disabled esmtp from the relayhost. I added
this line in main.cf "smtp_pix_workarounds = " and the problem went
away.
