I can live with that. I cannot live with skimming through 10,000 emails per day searching for the ~1 email every other day that is valid. YMMV [*] It's been several years since I've seen a report on how many unfiltered emails per day I received. 10,000 was the number back then. It is inconceivable that the number has decreased, by any realistic projection. -- Some people have a gift link here. Know what I want?

I checked through a bunch of emails in my inbox, and all of them got at least some score, usually between .5 and 1.5, even though they were all legitimate emails. That 5.0 is user-configurable -- In fact, for my Inbox, 3.0 or above is sent direct to trash. I spent a month or two with 10 filters sending every message to one of 10 boxes: Inbox.1 Inbox.2 Inbox.3 ... Inbox.10 As time went on, I found that only 1 and 2 scores were worth digging through, and lowered my SA setting to 3 and above is just auto-trash. And a couple mailing lists were going to higher scores, but those were easily white-listed. This would have been much easier had the email client let me sort by SA score, but that feature has apparently not been invented yet... YMMV, but it's amazing how much less spam I got once I let SA kill off all the junk it was pre-configured to accept. Course, I'm sure I'm losing some legit email as well, but it's such a tiny percentage, I just can't get too worked up about it. -- Some people have a gift link here. Know what I want?

Re: [PHP] Working with overly aggressive anti-spam measures [SOLVED]
Travis, Richard, Chris, Thank you for your helpful advice. I've managed to set the Return-Path correctly now, and Spamassassin is now only giving me the whitelist error, which I don't think I'm going to get rid of. It took me a little while to realize that the Spamassassin always says that an email is possible scam if it has any score above zero, but it takes a score of 5.0 to actually be deleted as spam. I checked through a bunch of emails in my inbox, and all of them got at least some score, usually between .5 and 1.5, even though they were all legitimate emails. So compared to other emails I'm getting, I'm scoring very low at 0.2. My emails don't use HTML, don't have any common spam key words, and have correct spelling and grammar, so it all helps establish my email's legitimacy. Here is the PHP code I'm using: $fromAddress = [EMAIL PROTECTED]; $fromName = My Name; $headers = From: . $fromName . . $fromAddress . \n; $headers .= Reply-to: . $fromName . . $fromAddress . \n; $extra = -f . $fromAddress; mail($toAddress, $subject, $content, $headers, $extra); Thank you all for your time and expert information. -- Dave M G Ubuntu 6.06 LTS Kernel 2.6.17.7 Pentium D Dual Core Processor PHP 5, MySQL 5, Apache 2 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
