Hi,
Ich hab einen neuen VPS-Server, der mir einige Probleme mit Timeouts gibt, die ich so noch nie hatte. Die Probleme tauchen bei manchen Providern bei allen Mails auf, bei anderen nur bei größeren (~800k = größer)
Das sieht dann in etwa so aus:
Mar 24 18:02:08 __HOST__ postfix/smtp[27831]: Anonymous TLS connection established to mail.XXX.org[XX.XX.XX.XX]:25: TLSv1.2 with cipher AECDH-AES256-SHA (256/256 bits) Mar 24 18:08:06 __HOST__ postfix/smtp[27831]: 7F4D8D486F7: to=xx@xx.xx, relay=mail.XXX.org[xx.xx.xx.xx]:25, delay=19438, delays=18916/0.03/169/353, dsn=4.4.2, status=deferred (conversation with mail.XXX.org[xx.xx.xx.xx] timed out while sending message body)
Passiert mit gmail, t-online, etc. aber auch mit einem anderen meiner Server, der normalerweise keinerlei Probleme macht, sodass ich da auch mal die Gegenseite sehen kann:

Eigentlich ist der VPS recht flott und reagiert schnell, ping zeiten sind sehr gut und ich habe ansonsten noch nichts bemerkt was langsam erscheint, aber aus irgendeinem Grund scheint das bei SMTP nicht der Fall zu sein. Ich hab sicherheitsalber iptables geflushed, falls da irgendwas blockendes drin ist, hat aber nichts geholfen.
Habt ihr eine Idee?
Danke!
