Unable to connect Manager Imap Email Function with 3rd party email accounts

I tried to connect email accounts like gmail,outlook,yahoo, and mail.com like any other email imap guides but did not succeed.

Any specific guides that I’m able to follow, like tips or tricks?

IMAP is not supported. You need to use SMTP.

oh… I did use smtp like smtp.gmail.com port 465 and other emails also unable to sent or connect. is it port problem?

I never had any problem with mozilla thunderbird. still wondering why I can’t apply to manager…

Port 465 is not supported. Try 587 port instead.

it works! thank you @lubos!
