In several of the sendmail.cf's I've got in front of me here, coming from all over the country, I find a mailer called "tcp-ok". Its definition is identical to that of the "tcp" mailer. In one of the configuration files, it is accompanied by a comment: # "tcp-ok" mailer bypasses the uucp->arpa forwarding check I see no mention of this in any of the sendmail documentation. Is this for real? -- Mark Sirota - University of Rochester, Rochester, NY Internet: msir@cc.rochester.edu Bitnet: msir_ss@uordbv.bitnet UUCP: ...!rochester!ur-cc!msir

Its definition is > identical to that of the "tcp" mailer. I posted that thinking that perhaps tcp-ok was some sort of special case in sendmail. After further investigation and a couple of responses (thank you), I've determined that these are just leftovers for some older version of the configuration files I have. Those configuration files that define it either define it just like the "tcp" mailer or only use one of the two. I figure that it must have been in one of the Berkeley samples sometime, and made it this far, even though it's now vestigial. -- Mark Sirota - University of Rochester, Rochester, NY Internet: msir@cc.rochester.edu Bitnet: msir_ss@uordbv.bitnet UUCP: ...!rochester!ur-cc!msir

The name of the mailers are arbitrary. For example, "tcp" mailer at our site is called "smtp" but I've seen some sendmail.cf files call it "ethernet"). The difference might be how they are resolved in rule set zero (i.e. the include file of the hosts these mailers can reached might be different). ------------------------------------------------------------------------- Disclaimer: The above are my personal opinions, and in no way represent the opinions of Intel Corporation.
