Re: [IMail Forum] blank host in kill file

Josh,       Not accepting Null Senders will get you on some major blacklists. Many Mail Server messages (mailbox full, etc.) use null sender, so it is required by the RFC standards.   Bill Green dfn Systems ----- Original Message ----- From: Josh Adams To: Imail_Forum@list.ipswitch.com Sent: Friday, June 23, 2006 6:18 AM Subject: RE: [IMail Forum] blank host in kill file Yes, I am getting e-mails 24/7 with blank FROM addresses addressed to various invalid users (valid every once in a while). These e-mails are coming from multiple servers. I suppose I could comb the logs and kill file the IPs instead. Do you think anyone would block e-mails out of my server for not accepting NULL senders?   Josh   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matrosity Hosting Sent: Friday, June 23, 2006 8:09 AM To: Imail_Forum@list.ipswitch.com Subject: Re: [IMail Forum] blank host in kill file   I wouldn't enable that. Your server is supposed to accept NULL sender by RFC standards. I assume you're trying to deal with spam? Josh Adams wrote: Wow, nevermind. I just found the refuse NULL senders checkbox. Does anybody have this enabled? Any issues?   Josh   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Josh Adams Sent: Friday, June 23, 2006 7:05 AM To: Imail_Forum@list.ipswitch.com Subject: [IMail Forum] blank host in kill file   Hello,   We are using Imail 8.05 and I was wondering if there is anyway I can make a kill file entry for when the ‘from’ address is blank? Has anyone tried this? Do you think there would be much benefit in doing this instead of having the blacklists reject the e-mail?   Thx,   Josh Adams
