After many years of working, this week we started to get this message on the client side when trying to send mail: Could not connect to SMTP Server: [Server Name]
This is happening on all our workstations.
On one of the severs we are getting:
on the other
On the first server, as the log snippet shows, up to a couple days ago the mail would go after a few tries. Now its not going at all.
On the second server it does not go at all.
All our other mail clients work. We use Outlook express, Microsoft Outlook, Evolution on Linux, Thunder Bird on Linux and Windows and Opera Mail.
I've been on this for a few days now and I'm at a total lost. The next thing left to do is to contact my ISP which is not going to be a good experience.
Has anyone been through something like this before?
PS: We host our own mail servers.
