Subject: [exim] Wishlist: Handle 4xx code as response to MAIL
Hi,

to answer a question in the wishlist:


| (146) 15-May-2000 M Allow SMTP error codes in retry rules
|
| This would allow special handling of certain errors from certain hosts. In
| particular, it would allow failing of certain 4xx codes.
|
| This is now available for 4xx responses to RCPT commands. Is anything more
| needed?



It seems that I need the same for the MAIL command. Some neighbouring hosts
(using sendmail) answer like this:

SMTP>> MAIL FROM:<username@???> SIZE=1234

SMTP<< 451 4.0.0 Sender domain must resolve

Lowering the retry time for this type of messages would be a nice thing. So
what I'm missing is "mail_4xx" in analogy to the implemented "rcpt_4xx",
like this:

    begin retry
    neighbouring.doma.in    rcpt_450    F,12h,15m
    neighbouring.doma.in    mail_451    F,12h,15m
