Hi!

Unfortunately, I was not able to apply this fix. The console returns an error saying "open of exim... failed: no such file or directory.

I checked the repo and the file is actually there.

Please help.

Thank you, this worked for me! Now my SMTP server works again.

Exim downgrade also worked for me.

However, shouldn't we understand the problem and fix it for newer versions of exim? It will be a bit annoying to go around avoiding updating exim every time we update the system.

I was also having 451 temporary local problem when trying to send mail using smtp . Downgrade worked for me on centos 7

I agree with @nmpribeiro
we should understand this!

ALSO while I can add to the email queue using roundcube in 4.9.3
my exim queue is stuck

saying
remote deliveries suppressed

Worked for me. Thank you very much!
Exim 4.94 wasn't signing the mails using DKIM, 4.93 does.

If you use the short url way, chances are the file is saved as JJjHP to fix this, simply rename that file:

Code: Select all

$ move JJjHP exim-4.93-3.el7.x86_64.rpm

I can confirm that this fixed the issue for me reverting back from 4.94 to 4.93
