Hello Wietse,
thank you for your response.
What would be the best way to debug, if the mail that wasn't delivered
was actually legit?
I lowered my restrictions for smtpd_sender_restrictions and
smtpd_helo_restrictions.
Could that have been the issue, that legit email was being rejected?
Best,
Lucienne

Hello,
some people on my mailserver are reporting that mails aren't getting
delivered or are getting deleted.
In my postfix logs I saw a lot of
```
Jul 21 13:14:00 myserver postfix/smtpd[1934175]: connect from
v3.t.example.com[18.18.18.18]
Jul 21 13:14:00 myserver postfix/smtpd[1934175]: ABBE1120157:
client=v3.t.example.com[18.18.18.18]
Jul 21 13:14:00 myserver postfix/smtpd[1934175]: disconnect from
v3.t.example.com[18.18.18.18] ehlo=2 starttls=1 mail=1 rcpt=1 rset=1
quit=1 commands=7
Postfix accepted EHLO, STARTTLS, EHLO, MAIL FROM, RCPT TO. Then,
the client sent RSET and QUIT instead of delivering an email message.
Jul 21 13:14:00 myserver postfix/cleanup[1934251]: ABBE1120157: removed
(canceled)
What does the "removed (canceled)" mean?
This means that the SMTP client sent MAIL FROM and at least one
RCPT TO, but did not deliver an email message.
Does mail get deleted if it says only "deleted"?
Postfix logs that for a received message, after Postfix has delivered
or bounced all recipients of that message.
The logging is primarily for logfile analyzers.
