Gilles, Thank you for a detailed warning. I really appreciate it. I didn’t want to stir this any more, and certainly don’t want to add to your grief and workload with the filters. Should I ever run into problems with smtpd, I will ensure that any testing I do will be with no filters enabled. Like I mentioned in my previous email, I’m aware that the filter functionality is experimental and that the testing intended is not of the filters, but rather the filter API in smtpd - and I understand what that means. I’m grateful for all the hard work you guys are doing with smtpd and certainly don’t want to hinder it in any way! Best Regards and sorry once again for causing you grief, it was totally unintended. mike -- Michal Krzysztofowicz http://antarcti.co/ | http://beautifulocean.org/ -- You received this mail because you are subscribed to [email protected] To unsubscribe, send a mail to: [email protected]
