Yes, those error were before I removed sendmail from the default config.



Even though it seems to be answering on post 25 now, mail sent to an

account there from Gmail are not being received. No errors in the

logs.

I am late to the thread (and I haven't a clue what we are talking about in
fact), but I get a 220 when I telnet into that IP address...

Escape character is '^]'.
220 mercury.localdomain ESMTP Postfix

Odd. Why would it say localdomain?

In fact Russ was here before me.... as he says, it is likely a connectivity
issue... not a mail issue.

He probably has an incorrect myhostname or mydomain value in main.cf.
From the look of the postconf -n he posted, he hasn't specified either
of these.

From the relevant section in Dotan's postconf -n:

mydestination = $myhostname, localhost.$mydomain, localhost
newaliases_path = /usr/bin/newaliases.postfix

The equivalent section in mine (sanitised because copying & pasting is
not the solution):

mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mydomain = example.com
myhostname = mail.example.com
mynetworks = 127.0.0.0/8, 192.168.1.0/24
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases.postfix

Got it! I had to set these three last values:
postconf -e 'mydomain = sharingcenter.eu'
postconf -e 'myhostname - mail.sharingcenter.eu'
postconf -e 'myhostname = mail.sharingcenter.eu'
postconf -e 'mynetworks = 178.63.65.136'
postconf -e 'mydestination = $myhostname, localhost.$mydomain,
localhost, sharingcenter.eu, mail.sharingcenter.eu'

I thank you guys for your patience and help. I just spent a good few
hours googling today and working my way around blogs, documentation,
howto articles, forum posts, mailing list archives, and the like. I
wouldn't have even known what to google for without the patient and
helpful assistance I've received here. When it is said that CentOS is
a "Community ENTerprise Operating System" be there no mistake!

Cold beer for anyone visiting Israel soon!

No problem.

Heh. It probably helps that I'm also subscribed to the postfix-users
mailing list, which frequently addresses issues like this. I highly
recommend it for anyone running postfix, even just as a lurker. Also,
Wietse posts regularly to that list.

If I could afford to visit, I'd take you up on that!
