Resolved Disable ipv6 qmail outgoing ip

[solucionesuno]

Hi,

I can change the ipv4 outgoing ip for qmail with ip route change ...

But gmail still uses the ipv6 address

¿How can i stop using qmail ipv6 adresss?

i need to change it cause gmail categorise my emails as spam. so i need to test with other ip address.

Hi,

Did you see my answer in topic Qmail outgoing IP ?

P.S. Can it be easier to solve a problem with false positive detection of spam? Do you add ipv6-address to SPF-record? Did you try to see into email headers of email marked as 'spam'?

Ip reputaton in senderscore is 87. but for ipv4. i am not really sure that te problem is the reputaton ip cause ipv6 seems not track sender score ip reputaton for my ip.



Really no more to do and I'm already in a state of panic with this problem.
Very frustrating

 

[solucionesuno]

@IgorG?

I have no idea.

Can you change qmail to postfix or you really need the only qmail?
Do you really need IPv6 on the server?

IgorG on vacation now.

I change to postfix and With postfix i can disable ipv6 and select another ip and works fine.

But when change to postfx i have other problem. some customer cant send emails. With error like server not support the securyty protocol

Issue - postfix/smtpd[*****]: lost connection after EHLO

I also think disable ipv6 ono server so qmail stop use it.

 

[solucionesuno]

If i remove ipv6 in ip adressses in plesk panel qmail must stop using it or ir have to disable in Linux also?
