Is that correct? I can't get a connection to port 25 on that machine -- something is dropping the packets. Might somebody have applied an access list to a router of yours, or perhaps your upstream ISP has put an access list in place? james -- James Raftery (JBR54) "Managing 4000 customer domains with BIND has been a lot like herding cats." - Mike Batchelor, on [EMAIL PROTECTED]
Re: qmail pop no longer works
the domain is ac.d4a.net. I am just really confused because it only happened over new years eve, and the computer running qmail was not even touched over that period. it worked flawlessly before then and no, i don't have a firewall thanks for your help Justin >Date: Wed, 3 Jan 2001 10:58:00 + >From: James Raftery <[EMAIL PROTECTED]> >To: [EMAIL PROTECTED] >Subject: Re: qmail pop no longer works > >On Wed, Jan 03, 2001 at 02:43:35AM -0800, Justin Cunningham wrote: >> the person that sends it gets those "warning: message undelivered for >> 4 hours" type messages > >Hi, > >It seems that something is blocking incoming SMTP traffic to your >mail server.

qmail pop no longer works
Ok this is wierd. after new years eve, i can no longer receive mail that is sent to me remotely through my qmail server. i.e i can send myself and others on my network email, but noone can receive mail that is sent from elsewhere on the net, the mail just does not show up, and the person that sends it gets those "warning: message undelivered for 4 hours" type messages i know i didnt change anything in my setup because i was away for new years. has anyone else had this? i can send (smtp) to remote comps perfectly fine, just not receive. any ideas? cheers Justin Sent with STUPID.COM's free email.
