O que significam as letras F T S R e E no Sendmail milter?

Question

Eu vejo no sendmail.mc milters linhas como esta:

Xclamantivirus, S=local:/var/run/clamav-milter/clamav.sock,F=T,T=S:4m;R:4m;E:4m

Eu sei o que é um soquete local. Mas o que significam as letras F T S R e E?

    

Answer 1

Todos, exceto "E:", são explicados em Digitalização de e-mail para vírus com ClamAV e Sendmail por Peter Kaagman. Reformatando e corrigindo alguns erros de digitação:

S=local:/var/run/clamav/clmilter.sock of course is the socket created by clamav-milter

F= tells Sendmail what to do if the filter fail, blank means act as if there is no filter. You could use "R" for reject or "T" for temporary fail.

T= determines timeouts:

S:4m a timeout of 4 minutes for sending to the filter

R:4m a timeout of 4 minutes for receiving from the filter

    

Answer 2

Encontrado explicação aqui para F T S R e aqui para E

S=local:/var/run/clamav/clmilter.sock offcourse is the socket created by clamav-milter

F= tells Sendmail what to do if the filter fail, blank means act as if there is no filter. You could use "R" for reject or "T" for temporary fail.

T= determens timeouts:

E= Overall timeout between sending end-of-message notices to the filter and waiting for the final acknowledgement. 

R= a timeout of "n" minutes for receiving from the filter
