No.
It's fine for your mail server to claim to be "smtp.nextlink.net", or for
your reverse DNS entry to point to smtp.nextlink.net (assuming that your
ISP doesn't mind). It's also fine for your to have your mail server claim
and reverse DNS entries to be smtp.example.com (where example.com is your
domain).
The problem is that your mail server is claiming to be "SMTP". Not
"SMTP.nextlink.net" or "SMTP.example.com", just "SMTP".

That won't make a difference -- IMail isn't answering the SMTP port. You
need to find out what is (a firewall or another mail server in front of
IMail, most likely).

That's not a problem -- the problem right now is figuring out what is
answering on port 25 (the SMTP port). It isn't IMail.
