Thanks for your replies. Meanwhile i have tested with some simple replacements in header checks.
/email@office/ REPLACE From: Office /email@hospital/ REPLACE From: Hospital With the above, the replacement works fine for multiple lines. Here are the logs: Apr 28 10:40:10 server postfix/smtpd[48572]: connect from unknown[remote system IP] Apr 28 10:40:10 server postfix/smtpd[48572]: 381C760324: client=unknown[remote system IP] Apr 28 10:40:10 server postfix/cleanup[48576]: 381C760324: message-id=<1682671210.212@company> Apr 28 10:40:10 server postfix/qmgr[48571]: 381C760324: from=<sender@company>, size=600, nrcpt=1 (queue active) Apr 28 10:40:10 server postfix/smtpd[48572]: disconnect from unknown[remote system IP] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Apr 28 10:40:10 server postfix/smtp[48577]: 381C760324: replace: header Received: from company (unknown [remote system IP])??by hres: From: Office Apr 28 10:40:10 server postfix/smtp[48577]: 381C760324: replace: header To: email@office: From: Office Apr 28 10:40:10 server postfix/smtp[48577]: 381C760324: to=<Group@email>, orig_to=<email@office>, relay=smtp.company.net[IP]:25, delay=0.25, delays=0.01/0 Anyway, the final result i want to achieve, is that the Subject will be filled with the RCPT To header part,like this /email@office/ REPLACE Subject: Office /email@hospital/ REPLACE Subject: Hospital But the replacement is not working. The received emails shows an unmodified Subject but the RCPT To field is empty.

Am I perhaps missing the right expression here and could someone give me some advice? Or is there really no way around Mailmunge or MimeDefang etc.? Any hints would be appreciated. Thank you.
