[cobalt-users] RAQ3 - If more than 10 MB of email - "AUTH SCRAM-MD5 or APOP to connect to this server" - please help.

[Charles Teton <info@xxxxxxxxxx>]

I really hope someone can help...

I have a RAQ3 which my wife and I use a lot. My wife works for 2 
multinational companies, meaning she gets between 10 to 30 MB of 
emails, mostly video files, a day...

Nearly always when she has between 10 to 20 MB of emails sitting on the 
server I start to get the following message in the logs:

Apr 26 08:35:27 www in.qpopper[5948]: **** at **** (****): -ERR [AUTH] 
You must use stronger authentication such as AUTH SCRAM-MD5 or APOP to 
connect to this server

At the same time, my wife is asked to enter her password again and 
again... To no avail...

If I move most of the files to a temp folder, and make sure its under 
about 10 MB, everything is fine again...

Please can someone tell me if this is a known bug with Sendmail and/or 
if there is a work around?

I've installed the following, plus a lot of the standard security apps, 
i.e. logcheck etc.
