[Mailman-Users] Rejecting spam at the SMTP level?

Hello, I've been running several Mailman lists for the past ten years or so. Unfortunately, in recent months some list addresses have fallen into the hands of spammers, which is a real headache. Even worse, one particular -owner address is receiving nothing but spam, and I don't assume

Re: [Mailman-Users] list-owner getting spammed

Hi, I was having this happen, but in my case there was a very easy way to get rid of it. Whoever set up that spam mailing list made a very big mistake. They chose to send their spam to the owner address *and* the address for posting to the list! Normally there is absolutely no valid reason

Hi, I'd say the domain does need to be fixed first. I recently encountered a mail server (not AOL) which refused to accept mail from my domain because I didn't have an MX record. As far as I can tell, it is not the individual AOL users who need to request whitelisting, but rather, the

Re: [Mailman-Users] Users complain, they don't receive mails from the list

Hello, This bounce message clearly indicates that your IP address doesn't have a reverse DNS entry. This is a standard lookup done as a part of spam fighting efforts. You need to get your provider to set the reverse DNS for your IP address to the domain name of your mail server if possible.

Re: [Mailman-Users] Problem with AOL

Hi, A while back, I was getting irregular AOL bounces. By that, I mean some messages would go through just fine, and some would bounce with the error "AOL will not accept delivery of this message." Very unhelpful, as you can see. Furthermore, if a message bounced, it was probably always

Hi, I have a weird situation I'm sure others have had, and I'm wondering if there's any way in Mailman 2 to deal with it. I have three subscribers to one of my lists who are on ISP's who do spam filtering at the SMTP level, rejecting with a 554 any message they don't like. And as so often
