The whole morning I keep getting error messages like this when I try to post anything:

General Error wrote:

Ran into problems sending Mail. Response: 421 Too many concurrent SMTP connections; please try again later.

DEBUG MODE

Line : 116
File : smtp.php

Sometimes the post is there anyway, sometimes it's not.

Anybody else having this?

No

i had one (I mentioned it on the 'too much money' thread)

I guess it's because there's loads of people watching a topic so it's sending out lots of mails at once when it's updated. But it seems weird that that's causing a problem all of a sudden...
