Spider: Duplicate emails in the SMTP events about iredmail

[iredmail]

If email has same value of email header Message-ID: and recipients as archived one, then it's considered as duplicate, hence it will be discarded. Did you check and compare the mail headers of archived and rejected ones?

Hi, thank you for the answer,

well, my postfix sends only 1 mail (verified). First of all I thought it sends two mails due to 2 entries in the transport file, but this does not seem to be the case. In spiderd log files I do not have any further information:

This is one entry for your information:

Any related info in Postfix log file? I expect Postfix logs 2 messages or 2 smtp connections.
