To Admins -> mails problem

Recommended Posts

Hi !

This message is for to the admins team.

Since you have changed the forum e-mail address name to out@rwg.com, there is a lot of problems with my (and probably others) mail servers.

This is a REAL HUGE mistake to use a host that does not exist, and does not match with your server IP...

Most of the mail services like Postfix WILL ban this kind of message automatically !

Here is an example of my mail.log :

Feb 20 02:00:50 s1 postfix/smtpd[14490]: warning: 95.168.161.220: hostname alpha.rwgforum.com verification failed: Name or service not known

Feb 20 02:00:50 s1 postfix/smtpd[14490]: NOQUEUE: reject: RCPT from unknown[95.168.161.220]: 450 4.7.1 Client host rejected: cannot find your hostname, [95.168.161.220]; from=<out@rwgforum.com> to=<romain@XXXXX.fr> proto=ESMTP helo=<alpha.rwgforum.com>

Why using "rwg.com" ?

Is it possible to come back to "rwgforum.com" ?

The e-mail system alert is really cool, please making sure it works with everyone :rolleyes:

The address I have changed to is out@rwgofurm.com and not ou@rwg.com, as you say in your post. Don't know where you get this from, as we don't own and/or control rwg.com. Most likely reason you are getting the error above is that I deleted the DNS for our hostname, so it was missing for a short while.

For those of you interested; the reason we have changed our e-mail setup and the reason some of your mail might end up in your spam-filters is that our domain/IP has for some reason been added to a lot of spam-blacklists(RBLS) that many providers validate e-mails against and this is not something we want.

Sorry T, think this could be partly my fault. I answered the question asked in the shoutbox yesterday saying to check spam or junk boxes for the new address (I've been getting them fine, but found one in the spam folder) but I missed the 'forum' part of the address in my answer.

Apologies guys!!

Hello Admin,

The log I posted is directly out from my mail server. The DNS name problem is now corrected :

Feb 20 23:06:34 s1 postfix/smtpd[1643]: warning: 95.168.161.220: hostname alpha.rwgforum.com verification failed: Name or service not known

Feb 20 23:06:34 s1 postfix/smtpd[1643]: NOQUEUE: reject: RCPT from unknown[95.168.161.220]: 450 4.7.1 Client host rejected: cannot find your hostname, [95.168.161.220]; from=<out@rwgforum.com> to=<romain@XXX.fr> proto=ESMTP helo=<alpha.rwg.cc>

But another DNS issue here. I don't see why the "helo" sent from your server is alpha.rwg.cc, when my mail server try to resolve alpha.rwgforum.com to your IP. Routing alpha.rwgforum.com to 95.168.161.220 will probably be a good idea.

As you probably know, DNS propagation can take anything from 10 second up to 72 hours (and more), so as soon as the correct DNS data is loaded for you, the problem will be solved ;)
