RT in one company sending to RT in another

I have an interesting problem.

One of my vendors uses RT, as do I. When I send a request to the
vendor, I do so through my instance of RT, putting myself (or whatever
employee made the verbal request to me) as the requester and the
vendor’s mailgate address as a CC:.

The vendor gets a ticket generated in his queue as expected, but I get
no “Thank you for contacting” message from his machine giving me his
ticket number.

E-mails that I send to his mailgate from outside of RT are answered
instantly, returning the On Create message like I expect. Any
subsequent correspondence from him (through his RT) triggers a copy sent
into my RT ticket, and I can send replies back through my RT to his
instance.

Something is obviously amiss here – his RT instance seems to become
somewhat befuddled by my ticket’s “[myexampledomain.com #xxxx] subject.”
Something in the “On Create trigger” is not working as expected.
Before I start digging into the source (and I’m no Perl guru) to figure
out why this is, can anyone offer the reason?

Thank you for your suggestions.

What versions of RT? What address are you sending from? I suspect some
of the “stop painful loops” behaviour is hurting you.

Hi Jesse, thanks for the reply.

My version is 3.4.5. His version is 3.4.4.

My mailgate address is it-support@mycompany.com. His mailgate address
is contact@hiscompany.com.

Thus, I add contact@hiscompany.com as a CC address.

That should work ok. (We’ve done it with customers before.)
