mail send not working anymore since update to 2020 spring

Post by borisCM » Mon Nov 09, 2020 9:52 am

Hi,

i'm getting smtp errors since the update to switch 2020 spring, anyone else had this problem?
we are working with a microsoft exchange mail server. before the update i did not had this issue.

Failed to connect to mail server; error message: Password authentication: SMTP protocol error. 535 5.7.3 Authentication unsuccessful.; NTLM authentication: SMTP protocol error. 504 5.7.4 Unrecognized authentication type.; CRAM-MD5 authentication: SMTP protocol error. 504 5.7.4 Unrecognized authentication type.; Kerberos authentication: Could not initialize security context (0x8009030c): Unknown error.

all the mail settings are double check by our IT department, the mail account is also still reachable via outlook and if we swith the authentication off, we do can get a connection, but off course we can't send emails
