slow delivery for big messages?

["Stuart Chase" <Stuart.Chase@MSVU.Ca>]

Any help is appreciated.

I have zmailer 2.99.54 running on Redhat AS2.1 for five months 
and until a couple of days ago, all was fine. No changes have been 
made to the system.

From this zmailer to one novell server, and only this one novell 
box, it is extremely slow delivering emails. This is especially 
noticeable when the emails have attachments >1 meg. 
In fact you can do a ps -ax |grep servername and watch the 
delivery process as it slowly moves the data across, 9%, a couple 
of minute later issue the same command and it is at 12% - this is 
on a 1.3Meg email!
All other connections to and from this zmailer server, including big 
attachments, are fine. The same is true for the novell box.

There is a way I can send the same large attachment to the zmailer 
server in question, which goes to another zmailer server (which has 
spam assasin and mailscanner), this other zmailer server delivers 
fine to that novell server. It seems that the problem is only with 
these two systems. They are on the same network, no routers 
between nor any rate limiting going on.

On the zmailer server, anywhere there is a server specific entry, 
the syntax for the entries are identical for problem and good 
servers. 

Anyone have a suggestion how to speed up or at least figure out 
why it is taking so long?

Thanks!
