I've been reading through these forums for a couple days now trying different things to resolve my problem with no luck. I followed the perfect setup guide and have had my ispconfig server running fine for a few months now. However I have noticed that I'm unable to send mail to certain domains such as AOL I guess because they block IP ranges that are considered residential. So I was going to use my provider's smtp to relay through, but haven't been able to get it working. I followed the directions listed here which would result in "relay access denied" errors. After talking to my ISP's support, they wanted me to specify port 557. I couldn't find any place to specify the port, so I put it after the smtp name, smtp.mailserver.com:557. After that, I didn't get the relay access denied message, but noone is receiving email from me either. Not even email users that worked prior to me trying to use my ISP's smtp server. After doing some more reading I came across a post saying to look up my domain at dnsreport.com. I noticed that under MX Category it failed with: ERROR: I couldn't find any MX records for millerx3.com. If you want to receive E-mail on this domain, you should have MX record(s). Without any MX records, mailservers should attempt to deliver mail to the A record for millerx3.com. I can't continue in a case like this, so I'm assuming you don't receive mail on this domain. And for the Mail connect to mail servers it failed with: ERROR: I could not find any mailservers for millerx3.com. I'm using my domain provider's nameservers and before I tried to add my ISP's smtp I was able to send and receive mail to/from mostly everyone so does that mean that I do in fact have an mx record? And does this even have anything to do with my problem? I'm just really confused at this point and not sure what to even try next.
