Hi experts, I get the following message when sending email to a clients address.

"the connection was dropped due to an smtp protocol event sink"

I also get the following message when sending email to any one at aol.com

"An smtp protocal error occured"

All other emails are sent ok, I'm using SBS 2003 r2 service pack 2!

Thanks for your response, I have done some further investigation and I beleive AVG may have something to do with it.

At first I had avg mail scanning disabled on outgoing messages, with this disabled I was getting the errors I mentioned in my first post and I was unable to telent to aol using "mailin-01.mx.aol.com 25" and in message tracking I would get "message transfered to    through SMTP"

I have re-enabled scanning and I now dont get these errors and am able to telnet, however when I connect I get the message "220 AVG ESMTP Proxy Server 8.0.192/8.0.196 [270.8.2/174] " and in message tracking i get "message transfered to avg through SMTP"

However emails still aren't received!

Update, I have checked AVG outgoing mail log and it seems like Ive still got the same problem as before, it just doesn't show up in message tracking anymore as the email is successfully passed to AVG where it then encounters the original problem.

one thing which seems strange is that the avg smtp connector tries to connect to an ip which resolves to a inty mail server and fails before going on to try to connect to the aol mail server and failing again. The thing that is strange about this is that the domain name i am sending mail from use to point to a inty mail server before it was moved to eukhosts.

I'm guessing I may have some dns issues here but i'm not sure what, the hosting was changed over a year ago without any issues. the mail server is setup to receive mail using a pop3 connector from eukhost which it does without any problems, it then sends directly using dns to route email.

Any ideas I'm really out of my depth on this one! Thanks

"message tracking i get "message transfered to avg through SMTP"

Are you sending messages outside using AVG or SMTP Connector ??? Check this in your ESM please, incase you find some Non-Exchange connector apart from SMTP / POP / IMAP / RG- please show us and i think its worth deleting

I am awaiting your response.

I assume I am using the sbs virtual smtp connector, under connectors I have a smtp and pop3. I have AVG small business edition installed running default settings.
