by Running Solaris x86 2.4 server on EISA box (3C579 NIC, Adaptec 2740
SCSI) and running SunSoft FireWall-1 v2.0. Machine's only function is
firewall and mail relay for ~250 users.
Most messages are fine, but some (~100/day) are deferred with
"Connection timed out during client DATA 250 with <host>"
Only some hosts seem to cause problem, no obvious common denominator --
some problem hosts are ESMTP, others Sun sendmail hosts, etc.
Problem goes away if I stop firewall. On firewall restart, the *first*
problem message will go through, all others queued will hang same way.
However, it appears that all messages to that same first host will now
go through.
Applied Recommended patches, including 102064-10 sendmail patch for OS
and 103336-05 for firewall, no change.
Any ideas?
