My ISP might be filtering port 25, I have no idea. BUT, I’m NOT connecting to my ISP as the mail log show. I connect directly to the recipients SMTP and get the right reply. That’s why I find suspicious that I get a bounce where the ISP is mentioned.
Unless they, considering this is Thailand, is intercepting network traffic if that is even possible. I wouldn’t be too surprised. > On 10 Sep 2023, at 15:42, postfix--- via Postfix-users > <postfix-users@postfix.org> wrote: > >> Sep 10 12:21:39 wopr postfix/smtp[25425]: 94E7840E5C: >> to=<recipi...@gmail.com>, >> relay=gmail-smtp-in.l.google.com[74.125.130.27]:25, delay=0.85, >> delays=0.03/0.04/0.56/0.22, dsn=2.0.0, status=sent (250 2.0.0 >> 38A5LeYj001108-38A5LeYl001108 Message accepted for delivery) > >> Reporting-MTA: dns; spamfilter-02.totbroadband.com > >> What’s suspicious here is the "Reporting-MTA: dns; >> spamfilter-02.totbroadband.com” line. > > > > Man in the middle?
