Default Too many connections from your host

Please Login to Remove!

We have approx 20 black berrys
When our SMTP mail server on some instances sends mails at similar times to the which routes to MX=[] {}, our sever confirms that there are "421 #4.4.5 Too many connections from your host".. Which I think is restrictions by the black berry end ?

Well I know we can limit out out going connections, but we have 20 black berry users who need to be on line and communicate at the same instance.

How can we ask hot to accept more connections from our fixed IP ?
