Hi,
Lately I have had many SMTP connections from 2 different danish ISPs, one
of them has 4 mailservers which keeps on making connections like the one below:
Jun 9 22:51:07 mpfgw1 smtpd3: 928961467.445214 tcpserver: end 29731 status 256
Jun 9 22:51:07 mpfgw1 smtpd3: 928961467.445660 tcpserver: status: 0/20
Jun 9 22:51:07 mpfgw1 smtpd3: 928961467.445905 tcpserver: status: 1/20
Jun 9 22:51:07 mpfgw1 smtpd3: 928961467.446159 tcpserver: pid 29734 from
195.41.46.139
Jun 9 22:51:07 mpfgw1 smtpd3: 928961467.446453 tcpserver: ok 29734
mail.relay1.webben.dk:195.41.48.111:25 fep4.post.tele.dk:195.41.46.139::57953
Is it their servers that are broken or is it mine ?
Its a bit annoying as they tie up lots of smtp connections which sometimes
causes my smtp server to timeout to other "good" connections.
So far I took the easy way out and blocked them in my firewall then theyll
need to deliver any mail via my mailrelay.
Well does anyone have an idea as to what could cause this ?
Thanks,
Thomas
