[SAtalk] question regarding spamc/spamd performance for large email services,and the spamc/spamd "protocol"

[Albert Croft]

Two questions, which I hope someone may be able to point me in the direction of resources for.

Question 1:
What has the performance of spamassassin (particularly the spamc/spamd combination) been like for mailservers handling medium-to-large quantities of in-bound mail (i.e., averaging on the order of tens of thousands or more emails per day)? In particular, in those arrangements where sendmail acted as the MTA, or as a scan-and-forward server to the final MTA. Have specific configurations been found to be more effective and efficient? What are some of the sizes of some of the larger sites using spamassassin?

Question 2:
Does the protocol use for communication between spamc and spamd support the ability to "stream" multiple messages, or must a connection be opened for each individual email arriving. If not, would the ability to do so provide any kind of performance improvement? Would such an improvement, if present, be worth the additional complexity such capability would likely add?

Thank you in advance for your time and assistance.

Sincerely,
Albert Croft
