Missing or Invalid SMTP Host

[Sam Laundon_58915]

I have used SMTTit Pro for years and recently have been having a problem sending emails to new clients that I have entered into the database. When sending emails to old clients I have not problem and I get the "email sent succsesfully dialogue box.

When I try and send an email to a new client I get: ERROR: Send: Missing or Invalid SMTP Host.

I send the same kind of email to all my clients so I don't know what is going on.

Here are the results:

Cleared All.

Host Cleared; Port set to 25.

Authentication set to Default: None

From Set to: <info@(email name removed).com>

Added Tos:

info@(email name removed).co.uk

CCs Cleared.
