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.
