Sorry about the personal reply, I didn't mean to be rude. Yes, the POP
connection did originate from the same address as SMTP, and I used to
cdbdump to check tcp.smtp.cdb. I found out today that Telia actually goes
through Safepages, and Safepages blocks everything on port 25 to any server
other than their own (126.96.36.199). After I was told that, I verified it
by dialing into one of their dialups and doing a port scan of our server...
25 was the only open port that didn't show up in the scan. The good news is
that POP before SMTP works beautifully for everyone else except those who go
through Safepages (or have port 25 blocked). So as an easy work around I
added mail.medzip.net pointing to 188.8.131.52 (medzip.net is another
domain we have, I'll be changing the pointer to something.powercalling.net
after we transfer the authority for the domain). For our normal users,
they'll continue using POP before SMTP with the address
mail.powercalling.net pointing to our server (184.108.40.206). Obviously, this
will keep spammers out since only those on the trusted IP range for
Safepages can use the pointer to 220.127.116.11 (others outside will get a
no relay error), and only our users who authenticate first can use our
servers. Thank you again for your help.
