Hello, after migrating from RT 3.8.8 to RT 2.4.10 last week, we are seeing issues with some email messages.
[29499] [Tue Apr 14 10:07:47 2015] [error]: Unable to parse an email address from x...@yyy.zzz <x...@yyy.zzz> : x...@yyy.zzz <x...@yyy.zzz> is not a valid email address (/opt/rt4/sbin/../lib/RT/EmailParser.pm:542) [29499] [Tue Apr 14 10:07:47 2015] [error]: Couldn't parse or find sender's address (/opt/rt4/sbin/../lib/RT/Interface/Email/Auth/MailFrom.pm:74) [29499] [Tue Apr 14 10:07:47 2015] [error]: Could not record email: Could not load a valid user (/opt/rt4/share/html/REST/1.0/NoAuth/mail-gateway:75) After some testing, I believe that the problem is caused by messages without a "Reply-To" header. Testing the same message in 3.8.8, the header "From" is used as "Requestor" if there is not a "Reply-To" header. Is this the expected behaviour in version 2.4.10?
