I normally do not look at the MTAs. When I looked at the MTA on out largest domain I see the message "Maximun Number of inbound connections (50) reached".

We are running GW2014r2 on linux.

How would this alert effect email traffic?

I have been reading that some people put a much higher number than 50. What be the effect of having a number too high?

We have about 400 users in this domain right now.

We have had some reported slowness on some out bound email traffic to the internet, could there be a connection?

Thanks
