sent mail being blocked by rDNS

Hello Experts,

My outbound mail is being blocked by "some" based on a rDNS lookup that shows my internal doamin name. IE: sbs.anydomain.local

The rDNS has been setup to be mail.anydomain.com same as my MX record and the inbound mail is working great...and it's only some of the mail being blocked.

Thanks!

required a firmware update to the Barracuda, and now it is sending mail correctly.

Thanks!

So the question is: How do I change the outbound name?

Thanks!

Might be that the sites are checking your SMTP banner...

When you say blocked, do you mean that your outbound emails are being tagged as SPAM or something?

I verified the SMTP Banner, and it is set for mail.anydomain.com and the DNS check button passes.

By blocked, I mean this:

You do not have permission to send to this recipient.  For assistance, contact your system administrator.

            <srv.anydomain.local #5.7.1 smtp;554 5.7.1 R:DNS - Message sourced from ipxx-xx-xx-xx.z169-154-67.customer.algx.net [xx.xx.xx.xx] not allowed. For assistance: see <http://info.smtp.ucla.edu> or e-mail <consult@ucla.edu>.>

The bounce messages claim that the .local rDNS lookup is invalid...which it is.

try looking at it externally, as it looks like your ISP is providing the DNS for your IP.

Do you have reverse DNS setup by the ISP?
