Very Computer

When my ISP tries to send large emails to me, I get errors every time
until it gives up and deletes the message.

I've tried snoop.  It seems to be sending the message just fine.
One odd thing was there were a few times where it appeared that the
sending side sent two packets without an intervening acknowledgment:

      *1 -> amusing.roc.servtech.com SMTP C port=2818 XzEvXC4yYS4xZTAxWzE2
amusing.roc.servtech.com -> *1       SMTP R port=2818

      *1 -> amusing.roc.servtech.com SMTP C port=2818 FhoQKxQWFhcVExMRFBUO
amusing.roc.servtech.com -> *1       SMTP R port=2818

Does anyone have any suggestions?

This is Solaris 2.5 talking over a PPP link (using dp-4.0 rather than
asppp).  The ISP is using Unixware.
