smtp connection test failed, mpc2050 memory clear all?

Hi all.. I have worked on a mpc 2050 in about 3h to get the connection test (smtp) on a mpc 2050 to work.

The coustomer IT tell me that it work on at least 4 other ricoh machine in denmark. This 2050 is in sweden. He have put in the right smtp serverver and add autofication =on and encryption=off

He continue say that they had a simulary problem whith a ricoh machine in Denmark that the technician made a factory reset on. After that reset everything work. Wonder if he mean memory clear all?
I can not see how an reset would solved this problem?

I just read that mpc2050 not support ssl over smtp, maybe there is a newer ricoh they use in Denmark?

They use windows 2008 server R2...
They had add ip from the machine so it should have acces.
I have upgrade firmware to 1.21
I have tried port 465, 587 and 25
He say that they use port 25 in Denmark.
anyone have an idea to try? Will ask if they use ssl on monday
