[GLLUG] Postfix or Exim?

[Ian Fitzpatrick]

Hi All,

It's slow season at the company I work for, and that means I can  
finally migrate them off our godawful Network Solutions hosted  
email.  I'm thinking to go with an Exim/Dovecot combo, and just  
wondering what people's thoughts are on Postfix vs. Exim.  I've used  
both, but only on testing or home systems.  I think I'm ready to pick  
up a book and really familiarize myself with one of these MTAs.

My requirements are pretty basic:

1.  Stable and secure
2.  Plays nice with dovecot
3.  Ease of administration (initial configuration not withstanding)
4.  Active and at least somewhat friendly development & support  
community
5.  Marketability:  This is a bad reason to pick technology I know,  
but I am kind of curious which of these are most widely deployed (and  
so which one future employers might look for in an applicant)

Performance is not much of a concern, we're a small company and only  
have 35 or so employees.

It seems like both Postfix and Exim could fulfill all of my  
requirements.  I read some comparison articles on the two MTAs, but  
it usually seems like it's a wash.  What might tip you in favor of  
one versus the other?

And while we're at it, if anyone can tell me a reason why I would  
should pick Cyrus over Dovecot, I'm all ears.

Cheers,
Ian Fitzpatrick
