Hi Zhang,

User A sends mails to multiple mailing lists which has more than 100+ users in each. The sent mail is delivered to all the users in the mailing list. In addition  the same mail is received multiple times (1000 times) to all domain admin users.


Note:  This scenario happens only when users send email to multiple mailing lists ( > 3). I will email you the mail log separately.
This incident happen twice for the same scenario.

Re: Mails getting duplicated for admin users multiple times for a domain

Hi Soundar,

*) It's hard for me to extract related info from a 46MB log file, please extract related lines yourself first. Don't be lazy.
*) You should at least tell me which domain admin received so many duplicate emails. Is this domain admin an alias account in /etc/postfix/aliases, or a virtual mail user?

Hi Zhang,

finally fixed  by modifying the below parameter in main.cf

virtual_alias_expansion_limit = 5000
virtual_alias_recursion_limit = 5000



Thanks
