My PEC mail sends me this error:

Sending username failed. The mail server mail.postecert.it responded: unsupported SASL authentication method

Can this be solved? Thanks

Right, but do you have mail.postecert.it, 993 (IMAP) or 995 (POP), SSL/TLS, normal password, email address, for the incoming? Does your antivirus scan secure connections? If it does, disable that option.

For the outgoing server, do you have mail.postecert.it on port 465, SSL/TLS, authentication method = normal password, User Name = email address?
