If setting .mc values doesn't work right, see SMM:08-61 (in
/usr/share/doc/smm/08.sendmailop/paper.ascii.gz) section 5.4 "M --
Define Mailer" - or just edit sendmail.cf, look for the Mprocmail line,
and add a "M=3000000," or whatever size you want. You can also do
N=<nice value> and various others.

I've seen this before, except rather than running on T1's it was to a
dialup SMTP that was accepting connections direct. Needless to say that
box was reconfigured to only allow from the backup MX's :)
