Zitat von "Josep M." <websur...@navegants.com>:
Hello. One spammer has tried about 300 times send me email, always from the same address, but from about 20 different IP . Never pass verify sender, always get 450 error....my question is...when one email fail postfix verify_sender 4 or 5 times..will be possible auto-blacklist this email for one week, for example? I use postfix 2.6.5 and postgrey 1.32
If it don't pass your restrictions, don't bother. If you built extensive lists of IP-addresses/e-mail addresses you have to manage those to prevent future errors so most of the time it isn't worth the effort.
