is your Zentyal server the one matching MX for domain shown in your profile ?

according to mxtoolbox, there is no obvious reason:

Code: [Select]
        SMTP Reverse Banner Check OK - 122.52.xxx.xxx resolves to mail.xxxxxxxx.com.ph
SMTP Reverse DNS Mismatch OK - Reverse DNS matches SMTP Banner
SMTP TLS OK - Supports TLS.
SMTP Connection Time 1.186 seconds - Good on Connection time
SMTP Open Relay OK - Not an open relay.
SMTP Transaction Time 3.931 seconds - Good on Transaction Time

although this addresses resolves to name that is not the part of domain reflecting your web site,ay,  so I'm a bit confused with your previous answer. Anyway, it looks like reverse DNS matches and this IP is not black-listed.

Then perhaps these recipients are using different DNS that is not updated with the right reverse.
Did you ago apply some changes less than 2 days ?
Is it also something that was working fine and then failed without any obvious reason like change or upgrade ?

Hello aspangilinan,

@ Christian;
You looked at the wrong server...  His hostname is zentyal.nsb.local and not the one that you looked at.


Back to the point;
1) SMTP banner (zentyal.nsb.local) doesn't match the PTR (very bad)
2) SPF is missing (minor)
3) Your IP is currently listed @ APEWS since 2008-04-27 (minor)

Also, I would strongly suggest you to install "DenyHosts" since your SSH port is open

So, what you can do about it (we all love solutions);
1) Change your hostname for the same thing that your PTR is showing
2) Create a SPF entry allowing your IP to send email from your domain
3) Visit APEWS and get unlisted (you may also contact your ISP for that matter)

APEWS website: http://www.apews.org/

** Just doing the first point should fix most of your delivery issues.

Best,

Marcus

Hello christian,

You are right - my bad.  I just checked in "private browsing" and I wasn't able to see his hostname & IP.

zentyal.nsb.local - does this exist on internet ?
Nope  :P  That is why I'm pointing it as "very bad"

Some other solution would be using the smarthost feature...

Thanks for your input and help - always much apreciated !

Best,

Marcus

 ::)

smtp:122.52.109.199 works but with performance issue + this server is blacklisted (CBL)
smtp:180.191.0.109 has problem with reverse DNS failure but is not blacklisted.

So each address has at least one good reason not to be accepted by remote MTA.

 :o :o
Do you understand what you are asking ?
basically, based on what I just tested, one of your server is blacklisted. What you are asking for is someone having an open relay so that you could hide your blacklisted server behind it  ::)

No, sorry, I can't help with this.
