From what I have read, and seen on the server SMTP is setup and running. I cannot send an email using my server. Prior to today, I had just used my ISP's smtp server. Now I have a client that needs to send mail through my server. So, I am using Thunderbird to test my mail server. I read my logs and found a problem and got that fixed. Now, it just times out. The error is that it has timed out.
I have setup smtp.myservername.com in DNS as an A record. Should it be something else?
As far as I know, port 25 is not blocked. I have a business account which allows me to run web and mail servers, so it should not be blocked.
I just need to be able to send.
