hi folks,

can anyone help me guess why mail has stopped arriving over the last few
weeks on a mailserver i setup a couple years ago?

/var/log/maillog shows for example:
Sep 27 14:35:10 pomcoweb sendmail[15045]: NOQUEUE: sc015pub.verizon.net [206.46.170.59] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA

this is happening for mail from earthlink, verizon, et al, though not
everywhere, eg mail from TCLUG is arriving fine.

we had never bothered to ask the isp to configure reverse DNS, so we now
thought maybe earthlink and verizon might be filtering on that, but we
got thzt setup now, and it's no better.

any ideas?

tia,
greg
