I know that it?s technically not allowed by various RFCs but can cyrus handle underscores in a host name and, if so, how? We have a $50 billion market cap corporation as a customer who uses underscores in host names and that?s apparently not going to change. If it can be done then great - if it can?t be done then it can?t be done ?
Version: Cyrus IMAP4 v2.2.12 [ESMTP Postfix (2.2.1) "Brand X"]
I was thinking at first that it was in the postfix arena but am led to believe that postfix does allow underscores and that messages being bounced (and deleted) by cyrus. Here are specific error messages from syslog:
501 5.5.4 Syntax error in parameters (in reply to MAIL FROM command))
501 5.5.4 Syntax error in parameters (in reply to RCPT TO command))
Here?s more complete entry from syslog:
