[COLUG] Re: Mail Server Advice

One thing to keep in mind when hosting your own mail server: how are you 
connected to the internet?

I have learned that some places will automatically drop any e-mail 
originating from a DSL or Cable Modem based IP address.  This is a way to 
avoid those spammers that use such networks, but it's a hassle when you've 
sent an e-mail and folks say they never get it.  For example, I was having 
an e-mail conversation with someone at my bank when one day they suddenly 
stopped getting my e-mail.  Unfortunately their IT folks didn't share any 
information about why this occurred, but other recipients of my email 
weren't having any issues; so all I can figure is that the email was 
dropped due to IP address.
