I have a brand new exchange 2010 install.  all is right with the world except that when domain users send mail to AOL, it is delayed and eventually expires.

Ideas?

Most email delays are caused by poor configuration.

Your SEND connector FQDN needs to say something like mail.yourdomain.com (not .local) and this FQDN needs to resolve back to the IP Address that you are sending emails from.

Your Fixed IP Address needs to have Reverse DNS configured on it with an FQDN of something like mail.yourdomain.com (to match your SEND Connector FQDN) and resolve in DNS back to the same IP Address.

If you are configured in this way - then please check on www.mxtoolbox.com/blacklists.aspx to make sure you are not blacklisted anywhere.

If you are still stuck, please post your domain name and sending IP Address for some specific advice.

Ah!  That will cause you issues.

AOL have tightened up security recently and have got much stricter about mail-flow.

Also - if you email my server with .local in your FQDN - I have a rule to reject you because .local is invalid.  It only causes about 1% of mail to be rejected on my server - but it is invalid and cannot be resolved, so needs to be changed.

Promote certifications in your email signature

Has your company recently won an award or achieved a certification? They'll no doubt want to show it off. Email signature images used to promote certifications & awards can instantly establish credibility with a recipient and provide you with numerous benefits.

ok, my send connector has mail.mydomain.com in it now.  however, I have no DNS entry for mail.mydomain.com.  When I do an nslookup on mail.mydomain.com, it comes back null.  I ONLY have a DNS entry for mydomain.com and all my mail goes there.

So, I'm thinking I need to change the send connector to read just mydomain.com

Also, with my ISP, I have no reverse DNS.  Reverse DNS points to SBC Global, my DSL provider.

your thoughts?

If you don't have a DNS entry for mail.yourdomain.com - you can add one (and ask your ISP to add mail.yourdomain.com to the Reverse DNS record for your IP Address) or change the FQDN to yourdomain.com, then call your ISP and ask them to add yourdomain.com as Reverse DNS to your Fixed IP Address, then you should be much happier to send to AOL.
