Davide, We have built a WebSite (ip : aaa.bbb.ccc.ddd). This site is sending email. (xxxxxx.com) We have added in smtprelay.tab : (to enable the site to send email directly with or without SMTP Auth) "aaa.bbb.ccc.ddd" "255.255.255.0" with TAB and newline. This was working fine before. Some of our customers have email account on the domain xxxxxx.com. We have upgraded to .73 and emails (from the site) are not sent anymore :-(( It was working before (mail from the site)... Now it's not working properly Any ideas ?
