SMTP authentication error on v10

1

hello, since the v10 upgrade I receive SMTP authentication errors from my mailserver
the error on the log of my mailserver is the following

SASL GSSAPI authentication failed:

of course on V9.x I got no problem whatsoever
I’m using SSL or TLS on port 507 or 465, I tried every combination with no luck

any ideas?
thank you

Diego

I think your issue along with a solution might be discussed here: Pop and Smtp password not recognized after upgrade to V10 - #13 by diego.martin
