Exchange prøver ikke alle servere jvf. DNS
Vi har en exchange 2003 server. Når der sendes post til folk der bruger cyber-city har vi problemer med at mailen ikke når frem.Den bruger der har afsendt mailen får en mail med beskeden "Could not deliver the message in the time limit specified. Please retry or contact your administrator.
" fra exchange nogle dage efter at have afsendt mailen.
Den bruger vi sender til sidder på c-mi.dk.
Jeg har kigget lidt på cybercity's mail opsætning :
> c-mi.dk
Server: temp.premitech.net
Address: 192.168.101.64
Non-authoritative answer:
c-mi.dk MX preference = 100, mail exchanger = mailgate.cybercity.dk
c-mi.dk MX preference = 10, mail exchanger = ywuser.cybercity.dk
mailgate.cybercity.dk internet address = 212.242.40.53
mailgate.cybercity.dk internet address = 212.242.40.4
mailgate.cybercity.dk internet address = 212.242.40.52
ywuser.cybercity.dk internet address = 212.242.40.146
ywuser.cybercity.dk internet address = 212.242.40.82
En test af de 5 servere giver :
ywuser.cybercity.dk. - 212.242.40.82 [Could not connect: Could not connect to mail server (connection refused by remote mailserver). NOTE: Per the RFCs, mailservers are allowed to continuously retry this server until it is back online, and not try other MX records (RFC2821 3.9).]
ywuser.cybercity.dk. - 212.242.40.146 [Could not connect: Could not connect to mail server (connection refused by remote mailserver). NOTE: Per the RFCs, mailservers are allowed to continuously retry this server until it is back online, and not try other MX records (RFC2821 3.9).]
ywuser.cybercity.dk. - 212.242.40.147 [Could not connect: Could not connect to mail server (connection refused by remote mailserver). NOTE: Per the RFCs, mailservers are allowed to continuously retry this server until it is back online, and not try other MX records (RFC2821 3.9).]
mailgate.cybercity.dk. - 212.242.40.52 [Successful connect: Got a good response [250 Ok]]
mailgate.cybercity.dk. - 212.242.40.53 [Successful connect: Got a good response [250 Ok]]
mailgate.cybercity.dk. - 212.242.40.4 [Successful connect: Got a good response [250 Ok]]
Mit bedste bud er at vores exchange server ikke prøver alle de serverne, men bliver ved med at lave retry på de første - der ikke svarer. Er det noget man kan ændre på i exchange opsætningen ?
