Trouble Sending Large Emails. How Disable Outgoing Scans?

I have Bitdefender 2009 internet security and I noticed I can not send large email attachment emails in either thunderbird or through webmail in firefox. Called my ISP and they said try Internet Explorer and that worked flawlessly. The tech guy thinks it could be the antivirus. So how do I disable outgoing scans?

Thanks.

Hello davidm71,

Start BitDefender switch to advanced view after that go to antivirus section, high light the shield tab. Press on custom level uncheckscan outgoing mail and press on ok. How big are the attachments that you are trying to send? Try to compress them and see how it goes. What you also can try is changing the time-out settings in thunderbird see here.

Kind regards,

Over a meg in Mozilla's Thunderbird was giving me a timeout. I think I fixed it by increasing the "mailnews.tcptimeout" key in Thunderbirds config file from 60 to 300. Though I still have a problem when in Firefox using the web mail service as the attachment uploads also timeout. Couldn't figure that one out. But this help page helped solve my thunderbird problem: Thunderbird can not send large attachments

Thanks.

Hello davidm71,

How big are the files that you are trying to upload? Try this increase network.http.keep-alive.timeout setting in Firefox. Follow these instructions how to get there. See if this helps.

BitDefender http traffic scanner could be the cause. Try this open BitDefender switch to advanced view go to the antivirus section press on custom level and uncheck scan http traffic press on ok.

The setting is already set to 300. I'll try to increase it by 60.

Thanks.
