Hi!
It would be nice to add a fallback relay if the server has a bad ip reputation (many use DigitalOcean as a provider).
For example i cannot send mail to hotmail at all
Does someone know how to add the fallback manually whitout breaking the configuration in KeyHelp?

Re: Postfix fallback relay
Good idea..
Re: Postfix fallback relay
You can use the MSN delisting. But... The last time I have fights over 3 month for delist an IP.
The software said: Requires Win Vista®, 7®, 8® or better. And so I installed Linux.

Re: Postfix fallback relay
You need to edit your postfix conf
/etc/postfix/main.cf
For smtp relay credentials
/etc/postfix/sasl_passwd
Then run the following commands
Restart Postfix
You need to manually edit the DNS Records to include your smtp relay on your spf records.
I wish KeyHelp will add a feature where we can customize default DNS records for newly added domains and ability to rate limit emails. BTW, Thank you for the awesome Control Panel
/etc/postfix/main.cf
Code: Select all
# specify SMTP relay host
relayhost = [mail.isp.example]:587
smtp_sasl_auth_enable = yes
# disallow methods that allow anonymous authentication.
smtp_sasl_security_options = noanonymous
# where to find sasl_passwd
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
# Enable STARTTLS encryption
smtp_use_tls = yes
/etc/postfix/sasl_passwd
Code: Select all
[mail.isp.example] username:password
Code: Select all
sudo postmap /etc/postfix/sasl_passwd
sudo chown root:root /etc/postfix/sasl_passwd /etc/postfix/sasl_passwd.db
sudo chmod 0600 /etc/postfix/sasl_passwd /etc/postfix/sasl_passwd.db
Code: Select all
sudo service postfix restart
