Re: Remember Munich?
It's not just pumping mail around, it's supporting the clients, browsers, scanning for spam/malware etc that all turn into a lot of work.
I seem to manage it ok, email server in house, only a small company but all our software is open-source and our server handles blocking spam and malware without any issues. It's far more reliable since it was all brought in house. The reason it was brought in house was not cost although that has been a benefit, but was because we had were tired of third party companies being unreliable. A third benefit of bringing it in-house was an increase in our understanding of email systems enabling us to do things we wouldn't even have thought possible before.
