Hello forum!

My company ordered me to deploy an MTA as an email relay in the cloud.

Now, RAM is at a premium, so I have to go with an MTA that's light in resource.

Which one do you recommend: Exim or Postfix?

Hi,
I use exim with dovecot, clam and spamassassin and find it very light. Here are the resources currently being used:

Code:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 1005 mail      20   0 64560 1476  716 S    0  0.0   0:00.02 exim


Obviously this will depend greatly on the number of users that will be connecting. Also, if you were also to setup webmail, roundcube is perfect ;)

for simplicity, especially with a basic mail relay, I tend to opt for Postfix.
light, lean, uber secure, uber configurable, and scales better than anything else out there (IMHO)
