I have a new email server (postfix/dovecot/mysql) with accounts
migrated from another server (different platform) and email addresses
with ampersands like "r&d@domain.com" that worked on my old email
server are not working now.
I'd like some help tracking this issue down.
Can anyone tell me if this looks like a postfix, dovecot or mysql issue?
Some log info follows. For brevity I'm just posting this log snip as
I'm thinking I will get a simple answer to this but I will be happy to
post postfix, dovecot or mysql settings in detail if they are required.
Thank you, Brad
