I'm running qmailtaoster for an ISP mail system, we just switched over from another mail server that was running in windows (hmailserver.com <http://hmailserver.com>) which uses the same [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> for username and password, and it worked fine with "my outgoing mailserver requires authentication" ticked in outlook or equivalent settings in other programs, but I have an issue with about 20% of my customers, with exactly the same settings we transfered the usernames and passwords so they matched on the new server, then switched over the A and MX records, all of a sudden they cannot send email, they can receive fine, just not send, they get an SMTP auth failure, I was wondering if anyone else has experience in using qmailtaoster for an isp and could offer any tips, we resell our connections from a wholesaler so we dont control their IP's thus cannot just allow relaying from a particular ip range, we need authentication.
Are they receiving an error about the RBL check? If so, you can either remove spamhaus from the blacklists, connect them to 587 istead of 25, or some other type of workaround.
