Hi all, In a post back in 2011 Larry Starr referred to using
md_check_against_smtp_server to verify email addresses ahead. http://lists.roaringpenguin.com/pipermail/mimedefang/2005-March/026240.h tml in this he has this line: if( $relaydomains{$domain} =~ /^smtp:\[(.+)\]/){ This reads a the value of a hash, it essentially takes the square bracketed mailertable entry to interpret the server to contact to check for a valid user. This works fine for 1 destination server but in some environments there may be a number of servers available to authenticate against, an MS Exchange network for example may have multiple Hub Transport servers. I wanted to extend this to include multiple MX which are defined thus: Domain.com esmtp:[9.9.9.9]:[8.8.8.8] And I thought that I had correctly figured the regex required would be: /^smtp:\[(.+)/) By taking out the escaped close square bracket then the match should be for a string that begins Smtp:[ With an undetermined number of any characters on the end. Then the plan was to split based upon the colon character. I have been unable to get this to work and trying to use DB_File in the way I would normally treat hash tables and disk files keeps telling me that my code is not blessed .... which I wold have thought is something that I would hear about in church! Has anyone managed to extend this excellent logic, which works perfectly for single MX, to allow for multiple MX ?
