Hi This may be related to my previous issue here: https://www.howtoforge.com/communit...ng-with-newly-setup-server-with-rspamd.82819/ I have upgraded to ISPconfig 3.2.0 and run the re-configure services and since than, again, the X-Original-To is not added anymore. master.cf was not changed. so the flags=DROhu for dovecot is still set, all good. main.cf i see that enable_original_recipient is set to no. The postfix default is yes. Why is this changed to no? delivery from postfix to dovecot has changed from LDA to LTMP -> this seems to be the main issue. Postfix LMTP does NOT prepend the X-Original-To header, so dovecot doesn't receive it and no mail filtering can be done based on the mail recipient. There would be a "hack" for postfix to add the X-Original-To header, but I won't go this way (http://postfix.1071664.n5.nabble.com/virtual-alias-maps-and-X-Original-To-td9124.html). I will change back to LDA in my main.cf and re-enable enable_original_recipient. Based on https://git.ispconfig.org/ispconfig/ispconfig3/-/issues/4792 I assume that if I remove the dovecot-lmtpd package (which probably got installed as "recommended package" or due to a tutorial on howtoforge), in the future a "reconfigure services" won't add the LMTP options again? It would be good if that would be pointed out somewhere in the documentation (or upgrade/release notes). Thanks. Still, the enable_original_recipient should not be disabled. Shall I open a bug/issue for that?
