I’m a newbie on the forum, so apologies if I’m being naive with anything - but we’ve been having problems receiving emails from some (but not all) of our clients. When they try send us emails, they get the Undelivered Mail message I’ve copied below.
I’ve also tried sending emails to myself from other accounts & I haven’t received anything in reply! No emails delivered & no Undelivered Mail messages!?
Does anyone have any suggestions what may be causing this? And why only some clients are experiencing this problem?
