Your problem

I have a problem with the bounce management.

I did everything as it was said here: Bounce management | Mautic and read so many posts about bounce management but haven’t found the answer.

Can someone help?

I am sending and receiving emails via my own server. Sending emails works perfect. Problem is with receiving bounces.

If I set a Custom return path (bounce) address with my email address bounce@domain.com in the Email settings than all bounced emails are sent right there to bounce@domain.com. It’s ok. But if I additionally set this email address (bounce@domain.com) in the Monitored Inbox Settings as well, my mailbox bounce@domain.com does not receive bounced emails any more.

I checked my server logs and found that every time it is a bounced email the delivery of the returning message is false. Every time it happens it tries to send returning message to the email address bounce+bounceXXXXXXXX@domain.com instead of bounce@domain.com.

See below an example log how it looks when I’m sending an email from Mautic (configured to send emails from address mail@domain.com) to the fake email address abcdefgh123@ffaakkee.com.

Be aware that even if I’ve configured (in the Email Settings) that Mautic should send email as mail@domain.com it makes the bounce+bounceXXXXXXXX@domain.com email address as the sender!

Is there any way to make Mautic send email as mail@domain.com and if the email is bounced make the message return to the bounce@domain.com address instead of bounce+bounceXXXXXXXX@domain.com?

Any help would be most appreciated.

All the best.

Did you managed to solve this?

Actually i have the same email address for bouces: bounce@domain.tls set in ‘Custom return path (bounce) address’ field, and it works.

But if i set something in ‘Monitored Inbox Settings’, nothing works anynome and even if i try to send an email inside contacts profile i get the same error 550 as above [bounce+bounceXXXXXXXX@domain.com]. Campaign emails sent also doensn’t work.

The same happens even if i do not set the’Custom return path (bounce) address’ field but fill the ‘Monitored Inbox Settings’ with the same ‘Mail Send Settings’ email address.

I’m testing Mautic 5.1
