Can´t send e-mails - authentication error

Hi.

Have You tried to choose "Automatic" in IMAP/SMTP encryption?

Hi darnok, 

Thank you for your reply. 

No, i don´t think the issue is with the e-mail configuration. If I the computer is in other network, the smtp works fine. 

When i'm behind the XG it doesn´t work. 

Nevertheless, before this post I tried automatic and it did not work. 

OK, thanks.
Could You paste screen o Your business firewall rule here?

Hi dasnoK 

Thanks for your reply. 

I don't have any business rules for now. I have these I'm sending. 

Please, if you need further info, let me know. 

Thank you veru musch for your concern. 

Please, move rule No 5 on top and check outlook.

If the problem will still exist, show us configuration of rule No 1 and No 5.

I think, You need only one business rule on top. Look a this pictures.

  

Hi, 

I put the business rule at top. It's asking for a certificate now, and the problem remains. 

Sending the printscreens of current configuration. 

OK.

What's happening when you disable rule No 5?

Outlook still wants to apply certificate?

When You apply certificate You can download and send e-mails?

Hi. 

I disabled rule nº 5, and it works, because business rule is configured. 

If i accept the sophos certificate, I can send e-mails. 

But I don´t want to install any certificate. I just want to send e-mail. 

Something is filtering the e-mail and forcing it to use the XG certificate. 

How do I disable that behavior ?

Hi, 

I deleted all rules and created a new one, allowing all traffic in-out. 

It's working smtp now. 

There is something weird I don«t understand. 

When i configure a firewall I like to be strict and granular in rules. 

I created a rule permitting DNS in-out and http/s in/out. 

I deleted the DNS rule because I found it suspicious that no traffic was on the DNS rule, and name resolution continued to work. 

Maybe smtp was not working because I had a specific rule for it. Strange.

If you do not want to see the certificate error message in Outlook, you need to edit the business rule and uncheck the IMAPS and POP3S scan.
