Question : MDaemon not collecting Domainpop mail

Hi all,
As the title says one of my clients has had a problem that started just before Christmas.

Around 18th Dec all external incoming mail stopped.
Outgoing mail is fine for a while then patchy
Internal mail is fine and stayed that way.
On the 29th incoming mail returns, with no changes to settings (for reasons I'll explain in a mo)
4th Jan incoming mail stops again.
Currently no incoming mail.

The reason why no changes were made to settings is that the client is with a fairly flakey web host that has in the past stopped their service for going over bandwidth quota (I say flaky as there is no telephone support, you have to email - see a problem there) and we were pursuing that as the source of the problem.

However the quotas have reset and the web host  co. have bumped the quota to 4x the previous, but the problem is still there.

I have noticed that from the clients server and from my own pc which is on a different network but using the same ISP it is impossible to ping the domain and that tracert bombs out. It is however possible to access their website via a browser.

The setup has been working for over a year and the webhost claim noting has changed their end and I know that nothing bar a few security hotfixes have changed on the server.

What really baffles me is how it went, came back  and then went again.

Any ideas of what I might try would be truly helpful as I am in the middle of a Mexican stand-off
with the ISP saying all is fine, as is the web-host, as are Alt-N

Many hopes and thanks

J.

Answer : MDaemon not collecting Domainpop mail

Under the Queues menu there are options to Freeze different queues.  In the current version these are represented as ticks, plus you get a warning, but on an earlier version the selection of Freeze was indistinct, and that did catch me out once.  That shouldn't affect DomainPOP scheduling, but maybe so in a consequential way.
