Currently We are running zimbra for local users and other server for online webmail server interface.Why multiple copies of mails are receiving in online domain users when sending mail to other local same domain zimbra users?

For Example,We have two email ids a@test1.com and b@test1.com in local zimbra mail server and also we have another mail server other then zimbra mail server for online web interface with mail id name as c@test1.com.If mails are sending to c@test1.com means duplicate mail issue happening.Is there anything needs to be done in zimbra mail server configuration to block multiple mail copies receiving in c@test1.com

We are using fetchmail with catchall server.Is anything can be done in fetchmail configuration to avoid this duplicate mail issue?

Help is appreciated and It would be helpful for everyone who are all facing this issue when they are using fetchmail

Anyone have solution?

Nobody have solution to avoid fetchmail downloading same mail again and again.Please let me know if you have implemented to use catchall server in zimbra latest version so that we can use yours instead of third party fetchmail.

What to use destination zimbra postfix mail directory in getmail configuration


Note:Fetchmail downloading same mail only if its send mail to both online and local user as i said in previous post

Kindly share getmail configuration to deliver catchall server mails in proper destination.Currently mails are delivering to postmaster but not to particular email account in zimbra server.

We have configured fetchmail to fetch mails from catchall server and delivering to domain ids. If we send mail to online domain user c@a.com along with local zimbra user a@a.com and b@a.com means online user receiving 3 copies (1 original copy+2 cc copy). How to avoid duplicate mails in postfix?

Is it possible to use relay host as only localhost in fetchmail?

Below configuration is used

poll remote-host proto imap envelope 1 "Delivered-To"
localdomains example.com: user catchall-user with pass "password" to * here


same problem when using getmail also. Please let us know if there any way to reject online mail accounts while fetching?

HEY
Fetchmail is not the proper method of delivering mails if you have a single domain for local as well as online then you should use relay host method.

E.x. Suppose you have a and b user on local Zimbra server and c user is present at other server but domain is same like a@abc.com then you can simply use relayhost on yiur local Zimbra it will search for local delivery if user not present locally then it will deliver to the SMTP server where user c is present.

enable_original_recipient = no

Parameter can be used to disable the duplicate msg issue in postfix.
