I followed the instructions on page 5 of http://wwww.howtoforge.com/perfect_setup_ubuntu704_p5 Now my primary website's e-Mail works - - I can use MS Outlook 2007 to send and recieve e-Mail from email@example.com but the test e-Mails show up in my gmail inbox as firstname.lastname@example.org I want to host several small business websites on my one server, without any appearance of cross site contamination, I don't want e-mail from business website #3, #15, or #23 to appear as though it comes from website #1. I want email to show up in the repient's inbox without a "web1_" prefix. I know this can be removed by eliminating the prefix in ISPConfig, but each user of each web must have a unique login, So I need some other method, because I want run more than one business personally. I want my business #1 customers to get emails from me in the format ace.frahm@business_1_domain_name.com Business #2 customers should recieve emails that look like ace.frahm@business_2_domain_name.com and ace.frahm@business_3_domain_name.com ace.frahm@business_4_domain_name.com ace.frahm@business_5_domain_name.com and so on. My first website (acefrahm.com) will be used for my personal homepage, the others for business, social activism, great causes, entertainment, etc. I may host several other sites for other friend's businesses too, each friend could have several business websites too, and they would need e-mail formatted as above too. Plus, if we should be so lucky to hire employees down the road, they too would need e-mail that "looks right" to customers, for each different business. The driving cause here is that customers will be extremely suspicious of any email with "strange" looking prefixes or suffixes, just like "web1_". I can't afford another computer right now, so setting up another server with ISPConfig without prefixes for every site is out of the question (it would be wasteful anyway,as this should be possible from one box). My second website is frahmbrothers.com I intend to sell some things there. as I mentioned above, I can use MS Outlook 2007 to send and recieve e-Mail from email@example.com but I can't use Outlook to send or recieve with firstname.lastname@example.org When I test settings with email@example.com using MS Outlook 2007 >>>>> Tools >>>>> Account Settings >>>>> Change E-Mail Account (for firstname.lastname@example.org) >>>>> Test Account Settings I get two errors, one for recieving e-mail, and the other for sending: Code: "Log onto incoming mailserver (IMAP):General authentication failed. None of the authentication methods supported by your IMAP server (if any) are supported on this computer." "Send test e-mail message:None of the authentication methods supported by this client are supported by your server." Plus: If I send an e-Mail from email@example.com to firstname.lastname@example.org it shows up in MS Outlook 2007 under the email@example.com inbox! it should go to the firstname.lastname@example.org inbox instead! These two errors are similar to error messages I got (with a 554 error) a few hours ago with my first website e-mail, email@example.com, before I ran the steps on page 5 http://wwww.howtoforge.com/perfect_setup_ubuntu704_p5 Questions: Are there similar steps (similar to page 5) that must be performed with every new website added with ISPConfig in order to make e-Mail function correctly for each new website? Is there some simple method to rewrite "FROM:" of e-Mails to eliminate "web#_" prefixes? A way that doesn't merge my e-Mail inboxes accross all the different sites? Why doesn't the installition of ISPConfig perform the proper mail configuration automatically? Why are all these manual steps needed? I'd rather be making content instead. Where can I learn the true meaning of all those encryption instructions on page 5, so I know them cold, and can help others solve problems the same way falko, till, and edge help us? Can you reccomend some e-mail list deamons for opt-in mailing lists?
