Hello, colleagues
For several weeks we experiencing difficulties sending e-mails to one of our customers.
When I look at Mail Delivery Reports see two strange things first is
"Connection timed out: SMTP timeout while connected to mail.server.com [themip] after sending data block (16,379 bytes written)"
When I try:
Obviously they use Firewall / barracuda
The second strange thing I see is in the Mail Queue Manager
And 5-6 more real email addresses from our server. Please help me
