Could some help me to find out where these mails are and to read or delete them?
Additional I would like to know the reason of this email(s).

I'm using Panel-Version 10.2.0 on Linux 2.6.18-028stab091.2 (Ubuntu).

Thanks a lot!

Hello and thank you.

The article is for Plesk 9.2. I'm using 10.2.0.
The hotfix file ist from 19.2.2010 with 149151 byte and the file on my system has a datestamp from 31.03.2011 and has only a size of 67.376.
Is this right to overwrite the newer version with the old file?
I'm anxious to do this on my live system without beeing sure to do the right thing.

What about switching to Postfix?

What about switching to Postfix?

Is it your proposal to switch to postfix?
The problem then is done?

I do not care what SMTP is running on the system but it must work ;-)

How can I switch?
Do I use autoinstall on command line, enable postfix and disable qmail? Is that all I have to do?
Or should I consider something else?

Thanks in advance!
