Hi,

I am also receiving the following error message: postfix: Command output: /usr/local/bin/maildrop: Invalid user specified

However, it only happens for some of my virtual domain names. For instance, emails for the lusostar.com and hjelte.com domains is delivered without any problem. On the other hand, no email is delivered for redbanktoastmasters.com or greenbrierpetsupplies.com. The virtual tables define the users for all domains in the same manner.

I am wondering if there is a buffer size limite for the user and/or the domain, so that the string gets truncated. Any information on this will be greatly appreciated.

BTW, mail drop has the same behavior if I try a command line: cat file | /usr/local/bin/maildrop -d user@domain

The configuration files have the following parameters: In main.cf: virtual_transport = maildrop

In transport: domain.name maildrop:

In master.cf maildrop unix - - n n - pipe flags=DRhu user=vmail arg=/usr/local/bin/maildrop -d ${recipient}

Thank you
