Trend Micro has been reinstalled on my desktop, I can receive emails in my mailbox (Mozilla Thunderbird) but am unable to send. Error message is "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.optusnet.com.au timed out. Try again". What do I need to do to fix?

Hello hmandejmatson ! Welcome to the community!

We understand that you are having troubles in sending emails. We would like to know more about your current computer's setup so we can identify what seems to be causing this problem.

May we know what email service are you using? Are you using any versions of Outlook or are you using a web based email service? If you are using Outlook, do you have the Trend Micro AntiSpam toolbar enabled on it?

We will be looking forward to our response. 

Have a wonderful day!

All the best,

Trend Micro Home Users Community

-I'm not a Trend Micro representative, but I like to give you some suggestion-

Hey hman,

2 simple steps to fix. You have to understand if it is due to a Thunderbird parameter changes or TM not properly set:

- Disable TM and check if outgoing emails is OK. 
If yes, kindly set TM.

- Email outgoing does not work even if TM is disabled.
Check at server outgoing emails in Thunderbird and double check at the parameters, (look at your provider support page to know the exact values).
Check also at windows firewall is something is changed (outgoing port is closed, thunderbird rule is going lost, etc)

Hi Max Slo

Correct me here if i am wrong, but TM does noting with Thunderbird!
Only if something is starting from Thunderbird, some program or opening a file then TM does something.

Kind regards,
Tom

You're right.

Step 1 is just to be sure that TM is not preventing Thunderbird to surf on the net. hman said that TM has been reinstalled, so maybe a a whitelist rule is missing.  Strange but, maybe. 

In any other case you're right, TM 'ignores' Thunderbirds if there are not files / plugins / URLs to check.
