sendmail ConnectionRateThrottle

[Martha Mueller]

I have been searching on the sendmail.cf option ConnectionRateThrottle. I have found HP Technical Manuals that indicate this option is for incoming mail only. Other threads seem to indicate it works to control the number of sendmail processes, both incoming and outbound. The same question about MaxDaemonChildren...some documents indicate it controls incoming mail only, other documents seem to indicate both incoming and outbound. What is the difference between these two options?

The version of sendmail is 8.9.3 on HP-UX 11.0

Thanks.

Hi Martha,

The way I've always understood it was that ConnectionRateThrottle controlled connections TO the server - implying inbound. But can also include mail destined outbound being sent by internal servers that will be relayed on to the outside by the server.
Whereas MaxDaemonChildren controlled the number of children processes, of any kind, spawned by sendmail as a whole. So i interpret that to being processes involving BOTH inbound & outbound mail.

HTH,
Jeff
