Is there a way to adjust the autoconfig server file?

Hello everyone,

My question is, is there a way to customise the autconfig server file? Currently it delivers IMAP, IMAPS, POP3 and POP3S as well as SMTPS and SMTP via submission. I would like to remove POP3 and POP3S completely from the autoconfig file and not offer them, is there a way to do this?

Furthermore, I have the question of how a client proceeds when SMTPS and SMTP are offered via submission. Which is used first and is there a prevention here? Is there anything against offering both?

I would like, if possible, only:

IMAPS (993) and SMTP via Submission (587) all other ports or connection types should not be offered in the autoconfig.

Regards!

If POP3 is announced as “not provided” via SRV record it will not be included in the autoconfig file.

SMTP is only allowed using STARTTLS, therefore both SMTPS and SMTP are secured by encryption. The same applies for IMAP.

heavygale Thanks for your reply! :-) Okay unterstand. Maybe you can have a look on this Issue here, because I have problems with my autoconfig and use traefik.
