Folks,
I've had about the worst 36 hours I've had in a long time. I thought I was going to experience a fairly smooth transition from a Sendmail server that has been a problem for sometime. Problem not in that it doesn't send/recv mail, but that it's old.
The problems I had with the new server ranged from 20,000+ messages getting caught by cluebringer, could not seem to get it turned off. Once I think I did, had no way to clear them out and deliver. I use a high end Mail Gateway/SPAM Filter Appliance (Red Condor/Edgewave MAG) and had nothing but problems getting the damm MAG communicate on port 25 reliably. I had a straight forward LAMP install. I operate a data center and run either Ubuntu Server or CentOS. Not a noob at Linux admin. Did a straight forward iRedmail install.
I had this new mail server set up and functioning well with a test domain, resolvable, etc. Everything seemed to be good to go. I spent a week or so syncing the email accounts between the two servers. Did my final sync during maintenance last night and dit the cut over. So that I didn't have to deal with updating DNS for a bunch of domains, I made it real simple. BTW, I acquired this Sendmail server in a company acquisition. They had no less than 15 sub domains for imap, pop, etc. Believe it or not, smtp, smtpauth, smtp-auth, smpt, smpp, smtt, etc. I digress... I changed the IP address of the new email server to that of the old Sendmail server. Cleared ARP on my Router and....
I guess where I'm going is I could sure use some help. Paid if needed. I'm not a mail server guru. My needs are simple, mail handling, webmail, not spam, virus, or grey listing. I have a 75k device that takes care of that for me.
Thanks....
