Odd "Incorrect Sequence Number" happening

[Scott Tuc Ellentuch at T-B-O-H]

Hi,

     Yesterday I upgraded my laptop from FreeBSD 5.4 to to 5.5 . I
currently have a very custom sendmail process using cyrus-sasl-2.1.22
to my private server. My sendmail.cf  has :

DSrelay:vjofn.tucs-beachin-obx-house.com
                      and
Mrelay,         P=[IPC], F=mDFMuXa8, S=EnvFromSMTP/HdrFromSMTP,
R=MasqSMTP, E=\r
\n, L=2040,
                T=DNS/RFC822/SMTP,
                A=TCP $h 587

     So basically any email I send is sent on port 587 to my private
server. It looks like the following on the server when its received :

     Once I did the upgrade, I'm having a weird problem. If I send an
email, everything is fine. If I "Bounce" an email from elm, which just
means to send the entire message intact to another email address (I do
this usually for html documents that I can't read properly if I just
forward it) I'm getting :

and when I get a failure message, it says :
