The problem seems to be in the rfc822ParseHeaders function that's in the include/Imap/Imap2Handler.php file. For some reason "From:" header that's in the $headers is missing the email address part there only containing the sender's name but the "Reply-To" email is fine. For example: From: JohnDoe Reply-To: john.doe@example.com

Steps to Reproduce

1. Create an inbound email account with corporate email
2. Load inbound emails
3. Reply to an email

You didn't fill in your PHP version...

Make sure it's within the Matrix: https://docs.suitecrm.com/admin/compatibility-matrix/

@pgorod I use the official Docker image, I'm not sure what PHP version is there. I'll try to check

[Kapustlo]

docker exec -it suitecrm php --version:

Actually after debugging a little bit more, all keys in the $ret (rfc822ParseHeaders) look fine, including the "From" header but I'm not sure where to look, so I'll give some more information if needed
