Hi,

It seems that 0.8.0Beta 1 has issues when using CRAM-MD5 for TLS authentication.

Log from e-mail server (Kerio Connect 8.5.2) with CRAM-MD5 enabled:

Code: Select all

The log from sabnzbd doesn't show anything particular useful:

Code: Select all

2015-09-30 21:27:48,792::INFO::[api:694] Sending testmail
2015-09-30 21:27:48,813::DEBUG::[emailer:80] Connecting to server mail.xxx.xxx3000

2015-09-30 21:27:49,772::ERROR::[emailer:37] Onbekende authenticatie fout bij de e-mailserver

The last line translates as 'Unknown authentication error'.

It seems there is an issue with the CRAM-MD5 implementation in the used email ibrary. Is there any way to get this fixed? I would really like to enable CRAM-MD5 on the mail server.

Which OS are you using?
Please note that we have limited email support, there are just too many different servers.

Hm, I did some quick Googling and found that CRAM-MD5 i being deprecated, so maybe I should leave it turned off

So, SABnzbd's "standard" TLS is good enough?
