Mail Server constantly down

[onaweb]

Hello,
Recently, I was have problems with people not being able to login and check e-mail. I searched the forum and found a solution to run defpackagemng.exe --fix, which corrected the problem. However, ever since then, mailenable is constantly going down. For instance if I reboot the server, the mail server will not come up. I have to remote into server, mailenable management and manually staart the services for list connector, transfer agent, pop service, postoffice connector and smtp service.

Any ideas?

Thanks,
Andy
