Hi, I hope, somewone can point me into the right direction.
Recently I added two blacklist-checks to our sendmail config: spamhaus zen and the list from the german computer magazin IX. The good news: Spam has been about 70%-80%, now it is about 20%-30%. The bad news: A lot of our users have problems sendig mails from there dial up DSL or mobile phone network connections. I'v looked up there IPs and all where on the Black lists or the PBL from spamhaus. So was my Arcor IP last night :-) The information from spamhaus is, to use SMTP Authentification (http://www.spamhaus.org/pbl/query/PBL042952). I thought, we do use TLS and smtp auth already, so I thought, users allowed to log in will be allowd to send. But I got the errormessage using Thunderbird 2, that our mailserver didn't support STARTTLS in combination with EHLO. Outlook-users do get the message, that our server didn't support SSL, the server error messagt is 250. I did some hours of googling and checked some sendmail docs, but can't find the error or missing config settinges. So where to start/how to debug this problem? What may I check? Thanks for any help and hint!
