Mail Transport Unavailable for specific email

Postby Teampouce » Tue Jan 14, 2020 12:32 pm

Dear All,

I need your help to debug a curious problem that occur only on a specific email address.

Let say for confidentiality the email with the issue is : john.doe@domain.com

Let say for confidentiality my email is : me@mydomain.com


I can send email correctly to all users in @domain.com except only one john.doe@domain.com

When we try to send an email to john.doe@domain.com logs shows :

Jan 14 13:12:31 push1 postfix/amavisd/smtpd[16472]: 4E4D1DE4F12: client=localhost[127.0.0.1]

Jan 14 13:12:31 push1 postfix/qmgr[19744]: 7D766DE500C: removed


If I use an alias of john.doe@domain.com like jdoe@domain.com everything goes well ; no error !

If I try to send an email using telnet by the hand to john.doe@domain.com everything goes well ; no error !

I verified transport map in following files nothing :
transport_maps = lmdb:/opt/zimbra/postfix/conf/relaybysender,proxy:ldap:/opt/zimbra/conf/ldap-transport.cf


It is like a specific "mail transport configuration" apply to only john.doe@domain.com.

How could check / debug this ?

Any help will be appreciated

Thanks in advance for your help
Best Regards

Dear All,

Finally I fixed my problem after correct permission issue on transport maps files.

Then restarted mta service.

Thanks
