Re: [twsocket] Simple SMTP text emails rejected for virus or spam
Hi Hoby, Specifically, the problem was that GoDaddy doesn't like parenthesis [( and )] in the from field. Thanks for your feedback. It is always good to know that the problem was not in ICS component. -- francois.pie...@overbyte.be Author of ICS (Internet Component Suite, freeware) Author of MidWare (Multi-tier framework, freeware) http://www.overbyte.be - Original Message - From: Hoby Smith h...@romans618.org To: 'ICS support mailing' twsocket@elists.org Sent: Wednesday, July 15, 2009 10:47 PM Subject: Re: [twsocket] Simple SMTP text emails rejected for virus or spam Well, I finally resolved this issue.

Re: [twsocket] Simple SMTP text emails rejected for virus or spam
It's possible that their filter recognize the X-Mailer header, try to remove or overwrite it in OnHeaderLine event. Also if the mail used multiple parts the MIME boundaries could be recognized as well. Many spammers use ICS.

Re: [twsocket] Simple SMTP text emails rejected for virus or spam
It is likely that - despite what they say - your IP or hostname is blacklisted. You should try to send the email, with the exact same program, from another computer (or even several computers) using another ISP. If the problem happend from anywhere, then it is a problem of the mail itself. For example, each eamil sent by ICS contains a header line X-Mailer: ICS SMTP Component V7.26. Maybe their anti spam check that line for some strange reason. You can easily change that lin by going into the source code. -- francois.pie...@overbyte.be Author of ICS (Internet Component Suite, freeware) Author of MidWare (Multi-tier framework, freeware) http://www.overbyte.be - Original Message - From: Hoby Smith h...@romans618.org To: twsocket@elists.org Sent: Wednesday, July 15, 2009 6:28 AM Subject: [twsocket] Simple SMTP text emails rejected for virus or spam Hello, everyone...

Re: [twsocket] Simple SMTP text emails rejected for virus or spam
Regarding the hard coded boundary strings I suggest to make them (or parts) component properties. Would be a good idea to create a property XMailer with that string. The default value would be the current value. Some trick should be used so that the correct component version is used even if the property is serialized because the component has been dropped on a form. I think of a kind of placer holder such as %VER% within the string. -- francois.pie...@overbyte.be Author of ICS (Internet Component Suite, freeware) Author of MidWare (Multi-tier framework, freeware) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] Simple SMTP text emails rejected for virus or spam
Francois said... 1- You should try to send the email, with the exact same program, from another computer (or even several computers) using another ISP 2- It is likely that - despite what they say - your IP or hostname is blacklisted. Thanks for the input Francois. I have indeed tested by sending through an alternate gateway and other methods. Same problem. Also, when I attempt to reroute through a gate SMTP, my gateway SMTP logs show that the IP blockage has been removed and that the target SMTP server responds with the virus/spam error instead of host rejection. So, I think they are correct that there is no IP blockage anymore. So, my ultimate conclusion is that, like you said, it is the email itself that they don't like. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
