SBS2011 does not receive external mail URGENT
Posted on 2014-03-03
I REALLY NEED INPUTS ASAP!!!! :-)
I have a customer with a Small Business Server 2011.
Sometime yesterday this server stopped receiving external mail.
Internal mail + outgoing SMTP mail is still functioning.
Everything looks normal on the server. Diskspace + mounting OK.
I have just been in touch with Comendo.com which is hosting the spam filter. Comendo confirms that all the ingoing mails is stucked here with and error saying something like "Insufficient system resources" from the SBS Server.
I have ran a test on DNSstuff which came our all right!
I can confirm, that the global IP has not changed.
I really need input :-)
