How to change HELO hostname for outbound SMTP sessions?

Question

Hi! 
 I'm facing a strange problem: My mailserver, which is behind an XG, recently get blocked by Cisco's SenderBase algorithm because it identifies itself with a wrong hostname when issuing the HELO/EHLO command. I've already confirmed that the mailserver does send the correct name ("HELO mail.mydomain.com") but Cisco told me, they were informed that my server sends a "HELO Sophos" instead! 
 That gave me a real bad reputation on their list and some SMTP server are already starting to refuse connections from my host. 
 It looks to me that the XG uses somekind of (transparent) outbound SMTP proxy which rewrites the commands my mailserver issues. 
 Is there any possibility to either deactivate this behaviour or, even better, to change the HELO hostname? 
 Thanks in advance...

I was facing the same problem but finally fixed it, my mails are no longer bounced, they're delivered just fine.

Solution: Go to Email >> General Settings >> SMTP Hostname [This will be used in HELO and SMTP greeting strings]. 
 In the Value of SMTP Hostname, put in your domain eg, XXXXX.com, XXXX.co.bk [but not hostname of your mail server as that will cause a loop back given that your firewall is just acting as an SMTP Relay] 
 
 I this reply is late but I hope it helps someone facing the same problem.
