Hello, guys! I've been debating with Sieve for a couple of days. When we configure some redirection in ispconfig, either CC or BCC, the email arrives for the main account, but the account that should receive the copy does not receive the message. Below the log of the server (Maillog) referring to the delivery of the email (I just changed the email addresses to protect them): Code: Mar 20 22:57:05 srv-exwb01 sendmail[22014]: w2L1v4Si022014: w2L1v4Sj022014: DSN: Service unavailable Mar 20 22:57:05 srv-exwb01 postfix/smtpd[21955]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <srv-exwb01.eximiaweb.com.br>: Helo command rejected: Host not found; from=<> to=<[email protected]> proto=ESMTP helo=<srv-exwb01.eximiaweb.com.br> Mar 20 22:57:05 srv-exwb01 sendmail[22014]: w2L1v4Sj022014: [email protected], delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=33744, relay=[127.0.0.1] [127.0.0.1], dsn=5.7.1, stat=Service unavailable Mar 20 22:57:05 srv-exwb01 sendmail[22014]: w2L1v4Sj022014: w2L1v4Sk022014: return to sender: Service unavailable Mar 20 22:57:05 srv-exwb01 postfix/smtpd[21955]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <srv-exwb01.eximiaweb.com.br>: Helo command rejected: Host not found; from=<> to=<[email protected]> proto=ESMTP helo=<srv-exwb01.eximiaweb.com.br> Mar 20 22:57:05 srv-exwb01 sendmail[22014]: w2L1v4Sk022014: to=postmaster, delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=34768, relay=[127.0.0.1] [127.0.0.1], dsn=5.7.1, stat=Service unavailable Mar 20 22:57:05 srv-exwb01 sendmail[22014]: w2L1v4Sj022014: Losing ./qfw2L1v4Sj022014: savemail panic Mar 20 22:57:05 srv-exwb01 sendmail[22014]: w2L1v4Sj022014: SYSERR(vmail): savemail: cannot save rejected email anywhere Mar 20 22:57:05 srv-exwb01 dovecot: lda([email protected]): Error: Sendmail process terminated abnormally, exit status 69 Mar 20 22:57:05 srv-exwb01 dovecot: lda([email protected]): Error: sieve: msgid=<[email protected]>: failed to redirect message to <[email protected]> (refer to server log for more information) This is the sieve log for the account: Code: sieve: info: started log at Mar 20 22:11:48. error: msgid=<[email protected]>: failed to redirect message to <[email protected]> (refer to server log for more information). sieve: info: started log at Mar 20 22:25:24. error: msgid=<[email protected]>: failed to redirect message to <[email protected]> (refer to server log for more information). sieve: info: started log at Mar 20 22:39:31. error: msgid=<[email protected]>: failed to redirect message to <[email protected]> (refer to server log for more information). sieve: info: started log at Mar 20 22:57:05. error: msgid=<[email protected]>: failed to redirect message to <[email protected]> (refer to server log for more information). The server has been configured using this tutorial: https://www.howtoforge.com/tutorial...l-php-pureftpd-postfix-dovecot-and-ispconfig/ Would anyone have any idea what might be happening? Thank you in advance for your attention.
