Thread: Postfix mail occasionally bouncing from google

-

i've set mail server send mail directly through postfix instead of using relay. of time working without problems, having occasional issue mail bouncing google. here example log:

feb 9 03:51:01 server postfix/smtp[20513]: connect aspmx.l.google.com[209.85.221.52]:25: connection refused
feb 9 03:51:01 server postfix/smtp[20513]: 6488448aa0: to=<xxxx@xxxx.com>, relay=none, delay=0.08, delays=0.05/0.01/0.03/0, dsn=4.4.1, status=deferred (connect aspmx.l.google.com[209.85.221.52]:25: connection refused)

in case server appears connecting @ google mail-qy0-f52.google.com. if attempt connect server using telnet on port 25 refused connection. oddly able ping it. message deferred , typically send in ~5-10 minutes when different ip address returned google. there way around issue, or google pointing me mail servers of theirs not active?

here example log successful send:

feb 9 04:00:39 server postfix/smtp[20576]: 6a4eb48dd4: to=<xxxx@xxxx.com>, relay=aspmx.l.google.com[74.125.113.27]:25, delay=578, delays=577/0.01/0.15/0.55, dsn=2.0.0, status=sent (250 2.0.0 ok 1265688039 24si15076331vws.32

in advance!

is server on dynamic ip? of time big email providers block coming directly dynamic ip.

bonjour à tous, j'essaie d'établir une communication entre une carte nodemcu exp8266 et mon pc en wifi via les sockets wifi. cela fonctionne plutôt bien mais le problème vient de la lenteur des instructions liés à l'écriture : par exemple client.write(buf) qui s'exécute en 200ms et est donc bloquante. comment peut on faire pour réduire ce temps d'écriture car c'est vraiment handicapant. merci a+ antoconde vous êtes sous windows? si oui c'est sans doute dû aux delayed acks quote if make network trace network sniffer such microsoft network monitor, tcp server sends tcp ack segment last tcp segment in tcp data stream in delayed acknowledgement timer (also known delayed ack timer). default, windows operating systems, value timer 200 milliseconds (ms). faut éventuellement gérer l'agrégagtion d'ack dans votre code pc en contournant les infos systèmes. ça améliorera un peu les choses - mais le problème est côté pc pas esp (pa
