Funny! The information was in the exact email you replied to. I guess
this shows how busy you really are :)

I really appreciate your work on Exim.

Before I upgrade, let me share two examples. (I am using a Debian
package, so I may just wait for the Exim 3.22 debian version.) A part of
my exim.conf is also below.

Thanks! Okay I see this today. Here is example #1:

2001-02-13 06:36:18 14R8Yj-00010K-00 mail4.cheetahfast.org

2001-02-13 07:02:36 14R8Yj-00010K-00 Completed

Two days ago it was in my mailq:

51h  9.3K 14R8Yj-00010K-00 <>
          knealy2@???


(I don't want it in the queue this long!)

I have had a bunch of log messages like:

2001-02-12 11:08:06 14R8Yj-00010K-00 == knealy2@???
T=remote_smtp defer (111): Connection refused
2001-02-12 11:09:49 14R8Yj-00010K-00 == knealy2@???
T=remote_smtp defer (-44): retry time not reached for any host

and:

2001-02-09 02:39:22 14R8Yj-00010K-00 == knealy2@???
T=remote_smtp defer (-44): retry time not reached for any host

2001-02-09 03:22:28 14R8Yj-00010K-00 mail.cheetahfast.org
[64.27.94.160]: Connection timed out

I can't seem to find where it originated though. But from looking at the
mailq (where it says <>) I guess it is a bounce message that keeps
retrying.


Here is example #2:

2001-02-12 23:09:54 14QqkR-0007Uz-00 Message is frozen
2001-02-12 23:38:03 14QqkR-0007Uz-00 Unfrozen by auto-thaw
2001-02-12 23:38:04 14QqkR-0007Uz-00 ** golfwhiz99@???
R=lookuphost T=remote_smtp: SMTP error from remote mailer after RCPT
TO:<golfwhiz99@???>: host mc4.law5.hotmail.com [216.33.151.136]:
550 Requested action not taken: mailbox unavailable
2001-02-12 23:38:04 14QqkR-0007Uz-00 ** golfwhiz99@???:
message retry timeout exceeded
2001-02-12 23:38:04 14QqkR-0007Uz-00 golfwhiz99@???: error ignored
2001-02-12 23:38:04 14QqkR-0007Uz-00 Completed

This was in my mailq on the 11th:

70h  3.3K 14QqkR-0007Uz-00 <> *** frozen ***
          golfwhiz99@???


(I don't want it to be in the queue for 70 hours!)

I think this is when it originated:

2001-02-08 05:04:31 14QqkR-0007Uz-00 <= <> R=14QqkQ-0007Ux-00
U=mail P=local S=3390
2001-02-08 05:04:36 14QqkR-0007Uz-00 ** golfwhiz99@??? R=lookuphost
T=remote_smtp: SMTP error from remote mailer after RCPT
TO:<golfwhiz99@???>: host mail.hotmail.com [216.33.151.135]:
550 Requested action not taken: mailbox unavailable
2001-02-08 05:04:36 14QqkR-0007Uz-00 Frozen (delivery error message)

(I think it is replying back to a spam message.)

My exim configuration has:

## delivery attempted on frozen messages if 8 hours old
auto_thaw = 8h
## 17/Jan/2001 reed -- don't try to send undeliverable bounce messages
# EXim FAQ #Q0508
ignore_errmsg_errors_after = 12h

And my retry configuration:
*                      *           F,2h,15m; G,16h,2h,1.5; F,4d,8h



My question is: how can I get messages like this to get "error ignored"
and "Completed" earlier? (Or why are they staying the queue for so many
days? I don't want to continue retrying to send bounce messages for more
than one day.

Thanks again for exim ... and your assistance.
