in my GW2014 SP2 system the mail transfer is running fine for one time after a rcpgrpwise restart. I created both mail to an external account and mail from this account to our system but nothing happened. If I restart GWIA again the mail transfer is started.

Because the transfer is running fine and all data is sent and received I think there should be no misconfiguration at all.

Is this a known issue ?

How can I get the transfer running without restarting GWIA ?
