>Organization:
Cybernet (Schweiz) AG
>Environment:
FreeBSD sauron.cybernet.ch 5.4-STABLE FreeBSD 5.4-STABLE #0: Fri Nov  4 12:39:01 CET 2005     root@balrog.cyberzh.ch:/usr/obj/usr/src/sys/BALROG  i386

Non-standard configuration: kernel with HZ=1000

>Description:
After upgrading system sources with CVS (which applies the sendmail-specific
patches mentioned in FreeBSD-SA-06:13.sendmail) and installing the fixed
sendmail (cd /usr/src/usr.sbin/sendmail; make clean; make; make install), we 
saw almost every outgoing mail connection failing in data phase with:

Mar 24 11:05:27 balrog sm-mta[91089]: k2O99C7t086063: to=<XXX>, delay=00:51:45, xdelay=00:00:00, mailer=esmtp, pri=3960342, relay=YYY., dsn=4.0.0, stat=Deferred: Resource temporarily unavailable
Mar 24 11:20:00 balrog sm-mta[91086]: k2O99C7t086063: SYSERR(root): timeout writing message to YYY.: Resource temporarily unavailable

with verbose tracing, this happens pretty immediately upon entering DATA
phase.

>How-To-Repeat:
send outgoing mail.
Note: sendmail-8.13.6 has the same issues.

>Fix:
Reverting to pre-patch sendmail.
