Ich bin jetzt schon ganz kurz vorm verzweifeln und hoffe das ich hier Hilfe finde...
Ich bin dabei einen eigenen Web- und Mailserver einzurichten.
Webserver läuft ach soweit ganz gut.
Der Server steht hinter einer Firewall, dass heißt ein Großteil der Ports gefilter sind bis auf:
smtp 25/tcp Simple Mail Transfer smtp 25/udp Simple Mail Transfer pop3 110/tcp Post Office Protocol - Version 3 pop3 110/udp Post Office Protocol - Version 3 imap 143/tcp Internet Message Access Protocol imaps 993/tcp imap4 protocol over TLS/SSL imaps 993/udp imap4 protocol over TLS/SSL pop3s 995/tcp pop3 protocol over TLS/SSL (was spop3) pop3s 995/udp pop3 protocol over TLS/SSL (was spop3)
das sind jetzt nur die die für Mailserver wichtig sind.
Ich benutze Ubuntu 7.10 Server und habe Postfix über apt-get installiert
Nun zum Problem:
Ich werde von allen Mailservern abgewiesen. Ich weiß nicht ob ich zum Senden an Emailadressen einen Relayserver benötige. Habe aber versucht das einzurichten.

.
und noch am Rande sollte ein Server mit fester IP nicht auch ohne Relayhost senden dürfen, oder brauch man den immer.
ich danke für jede hilfe
