Sent mails, being refused...

I can receive emails, but suddenly everyone are rejecting my emails.

Code: 
Jun  2 20:11:02 HOST postfix/smtp[2670]: 64FEB11460: to=<RECEIVER@gmail.com>, relay=none, delay=0.52, delays=0.23/0.08/0.21/0, dsn=4.4.1, 
status=deferred (connect to alt4.gmail-smtp-in.l.google.com[209.85.227.27]:25: Connection refused)


I can't send replies to anyone any more.
What is an issue here.

My domain is SOME_USER -at- starforce.biz
 
Code: 
Jun  2 21:21:50 HOST postfix/smtp[2859]: connect to mx1.bsdroot.lv[83.241.11.155]:25: Connection refused
Jun  2 21:21:50 v postfix/smtp[2859]: 168F211461: to=<alXis.......bXdroXt......lv>, relay=none, delay=0.12, delays=0.03/0.03/0.06/0, dsn=4.4.1, 
status=deferred (connect to mx1.bXdroXt.lv[B][83.241.11.155]:25:[/B] Connection refused)

Seems I've got blacklisted somwhere.
:P

I'll hit a road now, to get some beer! :beer
 
that's weird, because right now every smap is wellcomed on my server (ok, not welcomed, but not filtered)
I haven't finished configuring SmapAssasin etc

hmm maybe you have some error in firewall config? [however i'd expect different warning in that case]
 
Looks more like your ISP introduced outbound smtp blocking (which is pretty common on consumer DSL and cable). Install net/tcptraceroute and run [cmd=]tcptraceroute 209.85.227.27 25[/cmd] to see where the connection is actually refused. Try several smtp servers that are seemingly refusing connections. If there's a !A next to the last (failing) hop (traceroute(8)) your ISP prohibits smtp traffic and you should use your ISP's smtp server.

After the beer try:
Code: 
telnet 83.241.11.155 25
Looks like a firewall issue to me.

Whatever that IP address is, it is set to administratively deny (!A) connections to port 25. If it's your ISP gateway, my earlier suggestion is right: they may block smtp on their networks.

P.S.: traceroute -p 25 is something entirely different, and it doesn't reflect any port 25 blocking.
 
Yes, 82.193.208.1 is my ISP gateway.
That is also, what I've been thought, after doing this test.
In this case, my ISP started to block port 25, 3 weeks ago.

I'll contact them and ask to lift block for my IP. Hell I'll even request reverse IP entry.
