- The context of my enquiry:
Mail delivery is a dreadful foe on my new Debian 10 dedi. I am having again, for a new virtual server and its website, this weird issue in which thunderbird manages to get the mail in IMAP, no issues, while it won’t work on android apps (Gmail, Outlook), with the report the certificate doesn’t match the website. Gmail last shows mails that inbox received last May, over a month ago, so it still used to work at that time. Terminal commands like service dovecot status, and restart, display no problems, all good.
Having made sure letsencrypt was renewed manually recently, not having had to add an exception in thunderbird and using exactly the same server/settings/username/passwords information, I’m fairly confident it shouldn’t bug like that.
- My actual enquiry:
Please, would you know if there is a way to replicate in a terminal (a shell, I use SuperPutty at home) what a mail client does, when it fetches email by IMAP?
It’s a Debian 10 server, Virtualmin open source latest stable, Dovecot + Postfix.
This way, hopefully, I would obtain a usable error report, instead of the vague messages given by the Gmail and Outlook apps.
And with a usable error report, who knows, let’s be crazy, it’s possible I may finally manage to fix that issue, sigh.
Well, this is it. I suspect it simply won’t work with terminal commands, but I have little to lose in asking here.
Thank you very much if you can tell me!
Kind regards from France
