This is not the first time this has happened. It last happened about a month ago. Tonight it happened for a different reason. This time it wasn’t the size of the mbox (I’m not using mbox on this server). This time it’s the size of the log. $ ls -lha ~/.mailfilter.log* -rw-r–r– 1 dan dan

I ran into this problem today and spent about 2 hours trying to figure out what went wrong. I composed an email to the Mailman mailing list and never sent it, because I solved the problem. Here is that email: Subject: Cannot view archives via website Hello, I think this is solved, but I’m posting

I’ve taken to the concept of sending a copy of each incoming email to a second server, for backup. This could be achieved by an alias. Store them in mbox format. Use newsyslog to rotate it over time. UPDATE: this strategy is mentioned in Scenic BGP Route | TechSNAP 137 at about 0:47:30. As part

I decided to set up some of my mail servers to require certification authentication on the submission port (587). In my case, I want to forward mail from my server at home to my public servers out there on the Internet. I don’t want just anyone to be able to submit mail here, so the

Greylisting is an interesting approach to spam. I first started using it in the form of OpenBSD’s pf and spamd tools back in 2007. That said, I now let Google handle my incoming email. Today I was trying to get spamd-setup to run: spamd-setup: Can’t connect to spamd on port 8026: Connection refused I couldn’t
