Do you know if your ISP don't block your port 25 (many ISPs does) you could try smtp submission to use port 587 instead, just edit master.cf of postfix configuration and uncomment th line that says

Code:
submission inet n       -       -       -       -       smtpd
in
Or use SSL port 465. Just about every isp blocks port 25 unless you have a business account.

If I un-comment this line for port 587 to work, will port 25 still work? We use an inbound filtering company and they send to us on port 25. So our firewall rules only allow from that company on port 25. I need to be able to have our mobile users to be able to send and receive as well. So if I un-comment that line, will I accept on both port 25 and 587?

Yes it will still work. Your "filtering company" who are they?

I un-commented that line and all is working well.

Not sure what you have going on.

I moved the server from a datacenter to my home.
Port 25 is blocked for sending mail so I would like my server to mail using port 587.

Should I use a relay server like gmail? Or can my server send mail from port 587?

Ziggo.nl is blocking a lot of ports.

I think that the easiest thing to do would be to use ziggo's outgoing mailserver. (relayhost = smtp.ziggo.nl)
Some more usable info (in Dutch) here: http://e2b.org/5q

Edge, tnx for your reply.

When I use the relayhost of Ziggo is there a maximum of emails being sent?
I could use the relay host of Gmail but the thing I have seen is that google replaces the senders email adres by my email address :-(

I'm not with Ziggo, but I'm sure that there is a cap on the amount of emails per hour.

Other problem is that Ziggo's dynamic IP block is almost always blacklisted, causing other email servers to see any email from Ziggo as spam.

I've never used gmail as relay host so I can not help you with the gmail problem.
