The [MercuryE] section in my Mercury.ini file was completely missing....  I inserted the section and now it appears to be working.

Thanks Rolf 

Hi,

At present we are using MercuryS SMTP server, to deal with incoming email direct to our server, MercuryP POP3 server, I'm not sure quite why I have that turned on. MercuryO POP3 client to fetch email from an exchange server at our head office using MailDav, MercuryI IMAP server to enable offsite access to mailboxes and toe allow some users access to their old email if they are using other clients, and Finally MercuryC SMTP relay client to relay via a smarthost which will soon be biting the dust.

I would like to change over to MercuryE SMTP end to end delivery client but if I enable MercuryE on restarting Mercury I get an error register_listdu failed.  Once Mecury finishes starting only MercuryS and MercuryP are actually running.

 Is there something else I need to set up to make MercuryE start.  I am running Mercury  on Windows Server 2003.

There is normally no prerequisite for running MercuryE, the program just loads that DLL instead of MercuryC. You could try re-installing Mercury to make sure no file is damaged, and check the MercuryE section in mercury.ini as well to see there isn't anything that's broken there.

I did try re installing, that did not fix it.  I will check the manual to see what should be in the MercuryE section of mercury.ini.

By default the MercuryE section in mercury.ini is expected to look something like this:

[MercuryE]

Poll : 15

Timeout : 60

logfile : C:\MERCURY\Logs\MercuryE\~y-~m-~d.log   # Traffic logging file

Session_logging : C:\MERCURY\Sessions\MercuryE\   # Directory for session log files

Session_logmode : 0
