[imp] "Error Connecting to SMTP Server" - Having difficulty troubleshooting !

[Tim Smith]

michael,

Nonsense.

How do you explain the fact that .....

(1) I see "lost connection after UNKNOWN from
<insert_horde_server_name_here> " in the mail server logs ?  ;-)
(2) I can ping the mail server from the horde box
(3) I can manually authenticate via openssl s_client on the horde box.

Its not a network/port filtering issue.
