Hi ALL!

Few days ago I have got this errors in my maillog:
Milter: data, reject=451 4.3.2 Please try again later

I suppose that this error comes from my old version of spamassassin, I
have upgraded it to 3.2.4 version from 3.0.1 but tomorrow I have see
in my maillog this error again:
Milter: data, reject=451 4.3.2 Please try again later

My sendmail.mc contains this lines, that depends to milters:

define(`_FFR_MILTER',1)dnl
MAIL_FILTER(`clamav-milter', `S=local:/var/run/clamav/clamav-
milter.sock, T=S:4m;R:4m;E:10m')dnl
MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass.sock, T=C:15m;S:
4m;R:4m;E:10m')dnl
MAIL_FILTER(`scam-grey', `S=unix:/var/run/scam/scam-grey.sock, T=S:
240s;R:240s;E:5m')dnl

define(`confINPUT_MAIL_FILTERS', `scam-grey, clamav-milter,
spamassassin')dnl

Sendmail version is 8.14.1, clamav version is 0.92.1.
Sendmail server works as relay for local network, but nobody can't
send mails from local network when this error comes up.

Please tell what should I do to tell sendmail server to ignore this
milter errors and accept them for delivery even if one of milters
fail?

What can cause this problem? Why milter generates this answer to
sendmail?

Thx.

I don't think so:

Looks like your greylisting milter is doing its job.

Thank you for quick reply!

No, when scam-grey doing his job it looks like:
Mar 13 11:43:21 gate scam-grey[23979]: m2D9guOW008869: added
server.fann.com to greylist
Mar 13 11:43:21 gate sendmail[8869]: m2D9guOW008869: Milter: data,
reject=450 4.7.0 Temporarily rejected. Try again later.
Mar 13 11:43:21 gate sendmail[8869]: m2D9guOW008869:
to=<nvb@mydomain.com>, delay=00:00:01, pri=46678, stat=Temporarily
rejected. Try again later.

I think this reject error were generated by milter, when it can't
connect to daemon. At this night my clamd fall down, in logs I see:

Thu Mar 13 04:29:55 2008 -> SelfCheck: Database modification detected.

Thu Mar 13 04:32:01 2008 -> Not loading PUA signatures.
Thu Mar 13 04:32:01 2008 -> ERROR: Not supported data format

And until freshclam didn't work correctly again clamd didn't work, but
clamav-milter do. So I think this error comes from clamav-milter. It
is quite strange to me, because I haven't "F=T" option in my
sendmail.mc. So if one of milters falls sendmail just ignore them and
continue to work. But whats happens, when milter are live, but daemon
is not?
Is there any ways to fix this without modifying milter source code?
And changing they reply codes for sendmail, if they can't gain daemon?

Your clamav-milter needs to be configured not to send 451 when it
itself cant process correctly, if thats indeed what you want to
happen. The F=T is only for sendmail when it cant connect to the
milter.

So this is an individiual milter thing.
