Understanding pop3 logins

A very Useful link on understandin pop3 or imap login strings has been posted which will help. I can work my way around pop3 and smtp but knew nothing about imap. I’ve spent the best part of two days struggling to get our Exchange server back on the internet and working again and I’ll document more about this on Monday. Basically we ended up with not being able to email other Azur or K3 sites but could email everyone else….then I went in and cleaned up Active Directory and couldn’t email anything out unless I kept stopping and starting the smtp server. In the end I deleted and recreated our smtp routing connector and everything worked – just when we were starting to discuss reinstalling exchange 2000 – NOT a nice thing to contemplate at lunchtime on Friday afternoon.
