For the smtp, you only need 25. 465 is smtps and 587 submission - sub. 2525 is not needed either. For pure relay the 25 is the only port you need, external mailservers will not relay to any other port, unless specifically configured. Josef On Tue, Mar 8, 2022 at 1:54 PM White, Daniel E. (GSFC-770

Thanks, the messages in hold are mostly spams evaluated by rspamd. So my desire is "just" to clean them and not really send bounces back. On Thu, Nov 19, 2020 at 2:02 PM Wietse Venema wrote: > Josef Vyb?hal: > > Hi list, > > is it okay (meaning if I am unknowingly breaking something by doing it)
