We have a SBServer 2008 that receives exchange e-mails through SMTP and has been working fine for so many years now. However today suddenly the SMTP connection cannot be received.

Any ideas?

Can you telnet into the server? If not, what error do you get?

Primary reason for SMTP traffic stopping is a lack disk space on the C drive. That triggers something called back pressure.

There is plenty of free disk space. Does back pressure need clearing if there was a problem or once there is disk space does it just start working.

Check that your ISP hasn't made a change to its configuration or policy witout telling you, that has resulted in port 25 being blocked.

It shouldn't happen, ever, but it's been known to...

On other thing - is outgoing mail affected?

Saying there is plenty of space doesn't really help.
How much space exactly, and what size is the disk in total?

Back pressure should resume traffic flow automatically, you can force it by restarting the transport service. Although something should be logged if it is happening.

They have 24GB free. The total disk size is 118GB.

The server is up to date? Back pressure I think works on a percentage basis, unless the server is fully up to date - I think it was SP2 that introduced the lower limit of 500gb. Fuzzy memory - Exchange 2007 SP2 was a long time ago.

Is this problem still occurring? As I wrote above, Exchange rarely does anything without logging something. Have you attempted to telnet in to the server to see whether an NDR is returned?

I am very sorry but I have just checked and it has all cleared and everything is back to normal.

There was already about 25Gb of free space on a 100Gb disk (C:\ drive).

I did not change anything but it is now working. If I am honest all I did do is keep asking the email hosting company as I have a feeling they were to blame.

I am sorry that I cant tell you what it was exactly though.

Try and find out exactly what went on with mail hosting outfit, and if they give you a meaningful answer post it here. It may well prove useful to someone else in the future.

That does rather imply that it was an issue at their end!
