Think I answered my first question myself - messages we're
sending are all text, only ~5 - 10kb, so we should not be
bumping up against the limit.
Still interested in the second question though...

Following up with two specific question:
1) Could the MinFreeBlocks=100 setting in sendmail.cf be
causing this problem? The /var slice is only 1.9 Gb here,
with about half free.
2) Is it possible to overcome this constraint by:
- setting up a new drive with identical slices, only
expanding the /var slice, then;
- copying the files on the existing drive onto the
new drive?
Will the FreeBSD & other applications work this way or
must they all be installed freshly from scratch?
Thanks!

After poring over sendmail manuals, docs, readme's and
Googling extensively have not found the answer to this
question. What configuration settings regulate the
outgoing e-mail volume?
Have recently upgraded from FreeBSD 4.3 to 6.1 (i.e., did
new install of 6.1 on clean disk, installed current
versions of applications and moved files - on same server
as before, same processors/memory, etc.). Installed
Sendmail 8.13 using standard sendmail.cf & FreeBSD.cf in
/etc/mail.
Have a PostgreSQL database of 20k+ opt-in subscribers to a
newsletter. When I invoke the sending routine, sendmail
immediately spawns 20 - 30 processes (all I can see via
"top"), quickly sends out 150 - 160 e-mails (via
/var/spool/mqueue) then no more new processes are spawned
and the system returns to a listening state. No error
message in /var/log/messages, no clues in
/var/log/maillog, nothing in the PostgreSQL logfile to
indicate why the e-mails stopped sending.
FreeBSD's sysctl shows more than ample system resources
(mbufs, files, etc). Netstat -m reveals no denied
requests. Is there another FreeBSD mechanism at play? A
sendmail configuration setting I can tweak to ensure all
e-mails are sent? Any other ideas on a cause of this
behavior?
Have x-posted to the comp.mail.sendmail group with no
replies yet; sure would appreciate any help.
Thanks!
