Since the update to to 11.52 Build 18, I've been unable to receive emails from certain servers. The message times out with an error of :

2015-10-26 09:22:26 SMTP data timeout (message abandoned) on connection from ********.*******.com [***.***.***.***]:56423 F=<********@***********.com>

I get them from multiple different senders, and the email never seems to bounce, instead continually retrying to send the same mesage.
