Hello Forum,
I have 3 domains on my mailcow server, domain1.com, domain2.com and domain3.com. For each domain, there is an info@ mailbox, with a redirect prefilter that redirects incoming emails to my gmail account, and keeps it on the server:
redirect "myemail@gmail.com";
keep;
This was working fine up until recently. How, now for some reason, info@domain2.com no longer redirects incoming emails, when the 2 other info@ prefilters continue working just fine. No change has been made to the DNS MX, SPF, DKIM or DMARC records, ssl certs are all valid.
I narrowed it down to rspamd rejecting redirects from its own info@domain2.com email address, considering there is a bad signature for the domain. Again, it was working just fine up until recently. The mailcow server was updated a couple of days ago, but the issue was not solved.
Any pointers anyone?
Thanks,
Fred
