Dealing with Out of Office Replies

Hi All,

I'm just wondering how you deal with out of office replies using MailComment? I have MailComment configured to run on a discussion forum. All is working well, except that many of the e-mail addresses have automated "Out of Office" replies on them. Because these emails are replies to the notification, they have all the right headers to be processed as valid replies by MailComment. This wouldn't be such a problem if they were being validated as coming from the correct user (and placed in the moderation queue where they can be safely deleted), but in my case, the automatic replies are being validated as replies from user/1 (sysop) and published immediately.

How do I:

1. Prevent the out of office replies from validating as user/1 - the desired behaviour is that these messages will be validated as coming from the correct user and placed in the moderation queue?

2. Is there any way to use the subject line, which usually contains the string "out of office" to automatically detect and discard out of office replies?

Regards,
Matt
