Problem w/ incomplete transmissions since T1 upgrade

[bobcat]

Hi,

Last week we got our T1 switched from 256k data to 768k data and we've been having some problems ever since. It seems like whenever something from one of our servers has some extra spaces in it, the connection will hang. For example:

A page that looks like this will work fine:
<tr><td><b>Line Status:</b> </td><td colspan=2><select name=&quot;ostatus&quot; >
<option value=&quot;0&quot; selected>Any</option>
<option value=&quot;1&quot;>Print Order Acknowledgements</option>


However, the following will stall right before it prints this line:

<tr><td><b>Line Status:</b> </td><td colspan=2><select name=&quot;ostatus&quot; >
<option value=&quot;0&quot; selected>Any</option>
<option value=&quot;1&quot;>Print Order Acknowledgements</option>


Notice the extra spaces.

This affects e-mail as well, where e-mail both being sent to the outside world via smtp and people checking their mail via pop3 get hung sessions on certain e-mails all which I suspect have those extra spaces in them.

The e-mail/web server is sendmail/apache running on Redhat 8. Everything works fine when sending to an internal user and everything worked fine until last week when we did the upgrade.

I've tried changing just about everything I could on our firewall to help this out, moved the stuck e-mails around to different e-mail servers, moved the server outside the firewall to rule it out. The only things I can think of that it could be are either something's up with our Cisco router that hooks to the T1 or something on our ISP's end. I'm currently working with them on that but so far they're just as stumped as I am.

Any ideas what may be causing this?
Thanks,

I've also tried another web server, placed it behind and in front of the firewall and it too has problems.

This is very, very frustrating.
