TLS auth problem - TLS packet with unexpected length was received

Software Support

Hi, I’m using OJS 3.0.1.0 and I need to authenticated against a designated server that uses TLS
I’ve tried every possible combination . With smtp on, mails doesn’t deliver at all
and with this conf, my exim log shows this error, also the server administrator says the from name, shown in his logs as null

Any Ideas
Thnanks in advance

Hi @Marcela_Giussani,

In the configuration file you quote above, the SMTP setting is commented out, as it begins with a ;. Remove the ; or it won’t have any effect.

Hi @Marcela_Giussani,

For TLS delivery, you may also need to prefix the hostname with tls:// and use the TLS port number. This will depend on what your SMTP server expects/accepts.
