Slide 99 of 111
Notes:
When considering MTAs, there are typically five things to look at: Security, Speed, Standards, Monitoring, and Management. Classically, open source sendmail has failed more or less on each point, and alternatives such as postfix have done better.
However, more recently open source sendmail has greatly improved on the first three points, to the point where it is arguable which program is best under what circumstances.
Moreover, the commercial version of sendmail has made great strides in the areas of monitoring and management, feats which no other MTA I know of can begin to approach. We currently run postfix on all our externally visible mail servers, but weíll be happy to rip all that out and replace it with Sendmail Switch.
Sendmail Advanced Message Server is a very new product, and I believe that it will have ìone dot ohî problems like all software typically does. However, I also believe that it will probably be better than anything else available, even though it will still have some rough spots.
