Hi! Networkers,

I'm using postfix 2.5.6 and it works perfectly on our academic server

My postfix server seems to reject incoming email when "Mail From" contains "|" character

220 *********************
>> >>> EHLO smtp.sender.com
>> 250-smtp.example.com
>> 250-PIPELINING
>> 250-SIZE 15360000
>> 250-ETRN
>> 250-ENHANCEDSTATUSCODES
>> 250 8BITMIME
>> >>> MAIL From:<bounces+|306052-6-3997|@example.com> SIZE=249898 BODY=8BITMIME
>> <one.of.my.user@hec.ca>... Deferred: Connection reset by smtp.example.com.

Can it be solved ?

Any help will be appreciated

Thanks in advance,
Eddy
