Hi,
i´ve got a problem with one special host: mail.grafschaft.de
This host is connected via an SHDSL-Modem (Bridge) to our network.
it is unable to get mail from them, if there is an attachment, or the
mail is bigger than a few kb, i get a "timeout after DATA" error.
The sender is using an Exchange 2003 Server, but with an Borderware
MXtreme Mailfirewall (as smarthost).
I already changed the MTU of my server (ratsmail.nordhorn.de) as
mentioned in a few posts a bit lower (1448)
on all routers and our firewall (on our site) (SuSE Linux based) if
applied "disable ip path mtu discovery
# echo 1 >/proc/sys/net/ipv4/ip_no_pmtu_disc
a few days ago there were no problems getting mails from
mail.grafschaft.de. i don´t know what to do....
i already added:
smtp_data_done_timeout = 1000s
lmtp_data_done_timeout = 1000s
could someone me with that problem?
some snippets of tcpdump:
tcpdump: verbose output suppressed, use -v or -vv for full protocol
decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
