Hello,

dovecot sieve sends vacation replies with an empty FROM: field by default. Sadly my provider rejects such emails.

I tried to change this behavior by adding sieve_vacation_send_from_recipient = yes to the plugin section in dovecot.conf. But still vacation replies are send with empty FROM: fields. Is there any further setting i have to change ?

My Version is dovecot 2.3.16 (7e2e900c1a) on Ubuntu 22.04 .

Here is my setting from dovecot -n :

log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:~/Maildir mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_vacation_send_from_recipient = yes } protocols = imap sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } user = root } ssl_cert = </etc/ssl/localcerts/servercert_pub.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = # hidden, use -P to show it userdb { driver = passwd } userdb { driver = passwd } verbose_ssl = yes protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve postmaster_address = torben@garfield.no-work.to quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r }
