EFA - to TWO Mail Servers

[bas60]

I have EFA configured for two Mailservers

abc.com, xyz.com - I've set both MX records to point to EFA

(1) is local LAN IP 192.168.1.250 for ABC.com server - email is cleaned and passed on to mail server ok
(2) is our 2nd office Static IP: xxx.xxx.xxx.123 - I can see email in EFA but the external sever never receives

If I configure the MX record to xxx.xxx.xxx.123 ie. the Mail Server's IP - I can receive email OK
I can ping and TELNET to the external IP from The EFA box

but the External IP for the 2nd Mail Server is not getting the mail - If I locate a temp server for the 2nd domain on the LAN mail is received OK!

How can I check why mail is not being forwarded ?
(no firewall etc)

and what happens to the emails EFA does not pass on !!?

is there a way to see what is in the queue ?
is there a way to force a connection ??
