SMTP Relay Redirect to TCP/26
I have three proxy servers (SMTP relay) that I want to put behind my F5's. I will need to create an iRule to redirect SMTP to TCP/26 (SMTP relay servers are listening on TCP/26). I found some samples online and tried to create an irule (below) but it spat up an error. Thanks in advance! when SMTP_REQUEST { SMTP::header replace Host "[SMTP::host]:26" }283Views0likes1CommentManage SMTP traffic to multiple tiered mail servers?
I would like to start using our new F5's for managing SMTP traffic to our different SMTP server groups. I have 3 groups of SMTP servers each group. Currently an HAproxy server is used to send SMTP traffic to the correct tier based on the port it receives the traffic and sends the traffic to a specific server in the tier by weighted round robin. Tier1 port 2501 Tier2 port 2502 Tire3 port 2503 I was thinking I'll need to create 3 separate pools that will have the list of SMTP servers and have Ratio load balancing set for the pool. Then create 3 virtual servers with different service ports 2501, 2502 and 2503. Finally creating one VIP that all the servers can send their mail traffic. Will this work or is there a better way with the F5 to implement a multi-server multi-tier SMTP setup like this?189Views0likes1CommentLoad balance SMTP traffic to a specific pool member based on the "FROM" mail header
I have a VS consisted of 5 email servers and would like to create an irule that would tell the F5 to route traffic to a pool member based on the "FROM" address. For example: a. user1@acme.com --> mail server 1 b. user2@acme.com --> mail server 2 c. user3@acme.com --> mail server 3 d. user4@acme.com --> mail server 4 e. user5@acme.com --> mail server 5 any help would be greatly appreciated!308Views0likes3Comments
