Hello, after new install
NAME=“Ubuntu”
VERSION=“20.04 LTS (Focal Fossa)”
ID=ubuntu
ID_LIKE=debian
When I try to send Email I get Error:
SMTP Error (421): failed to add recipient „[email protected] “ (Unexpected failure, please try later).
/var/log/exim4/mainlog returns:
2022-01-17 19:51:53 Taint mismatch, string_vformat: lsearch_open 35
Any Ideas what could be wrong? If You need any other info to debug just ask Thanks in advance.

Exim is a Mail Transfer Agent. It is normally called by Mail User Agents,
not directly from a shell command line. Options and/or arguments control
what it does when called. For a list of options, see the Exim documentation.
There is one problem with receiving mail too.
If I send test mail from Gmail acc I wont receive it.
If I send mail from Contact form on same domain there is no problems.

This depends on your OS and the available version on the related repository. Hestia doesnt provide any exim packages.

I am using Debian 11 as test server.
For Ubuntu 20.04 the last version is
Exim version 4.93 #3 built 28-Apr-2021 13:19:17
For whom it may concern: I have found a solution to this bug and posted it here: Exim4 mail sending issue
In short: go to the /etc/exim4/domains/(your domain name) directory and remove/rename files named ip and fwd_only
