Addrss rewrite agent(formula language) useful in migrations etc.
XXX—Current Domain
yyy—-replaced domain
It can be used by holding the mails & then running the agent on it & releasing the mails finally.
FIELD SendTo := @If(@Contains(SendTo;”@XXX”);@ReplaceSubstring(SendTo;”@XXX”;”@yyy”);SendTo);
FIELD CopyTo := @If(@Contains(CopyTo;”@XXX”);@ReplaceSubstring(CopyTo;” @XXX”;”@yyy”);CopyTo);
FIELD BlindCopyTo := @If(@Contains(BlindCopyTo;” @XXX”);@ReplaceSubstring(BlindCopyTo;”@XXX”;”@yyy”);BlindCopyTo);
FIELD Recipients := @If(@Contains(Recipients;”@XXX”);@ReplaceSubstring(Recipients;”@XXX”;”@yyy”);Recipients);

Do you know how we can have by default the BCC field filled with another email address ( i.e. forward all sent notes msg to gmail for eg.)
you can use server or client based rules for it, or create an agent as well.
Where do I put this code in? The Domino Server? Do I use designer and what location and database? Thank you for your help.
yes, you have to use designer & the database is mail.box(add it to all mail.box files you have)
This is located on domino server..
Thank you for replying so quickly. We are in a middle if migrations. And we are having the problem with external users emailing us. How does the agent trigger? Do I create a new agent as a formula? I just copy and paste the code? Again thank you.
What you have to do is hold emails when ever it arrives to domino servers & then schedule this agent to run every 5 mins , it will rewrite the address & release the emails. This is the way how we used it. yes just copy & paste the code as formula agent.
