One of my accounts was having login failures when trying to send mail, but was able to check mail. I tried everything I could think of to see what the issue might be, but eventually went in and reset the password in the sql database (I knew the password, so I reset it to the same password). {SHA256-CRYPT}$5$VuS? {SHA256-CRYPT}$5$VI7? So the password was updated properly. Clients can still

Hope to get some attention about this idea to reduce hacking passwords. Here is a list of about 700,000 IP addresses that are hacking passwords through SMTP AUTH http://ipadmin.junkemailfilter.com/auth-hack.txt This is a list of IP addresses that attempted to authenticate against my fake AUTH advertizing on servers with no authentication.

Hello to all members. I am using Dovecot for 5 years, but this is my first post here. I am aware of the various autoresponder scripts for vacation autoreplies (I am using Virtual Vacation 3.1 by Mischa Peters). I have an issue with auto-replies - it is vulnerable to spamming with forged email address. Forging can be prevented with several Postfix settings, which I did in the past - but was forced

I am used to sendmail and am using Postfix now and am uncertain of some features. I typically would comment out the line in sendmail.mc that went something like 'accept unresolvable domains' I tried using smtpd_sender_restrictions = reject_unverified_sender reject_unverified_smtp and this seems a bit too restrictive and got some bounces on legitimate senders so I'm
