I had a problem on Ubuntu server. Some guy has added his e-mail somewhere and the server tried to send him e-mails. So Google responded, that it was spam and blocked them. I have searched using grep in logs this way:<\/p>\n

\r\n\/var\/log # grep -n \"guys_name@gmail.com\" *\r\n<\/pre>\n
And got this kind of entries in mail.log and others: <\/p>\n

For a while I couldn’t find a problem place and didn’t know, where to fix. I tried to list cron jobs:<\/p>\n
\r\nfor user in $(cut -f1 -d: \/etc\/passwd); \r\ndo \r\n  crontab -u $user -l; \r\ndone\r\n<\/pre>\n
But without a success.<\/p>\n
Finally, I did search using grep recursively and found some files, where this e-mail appeared: <\/p>\n
\r\nroot@lovecakes \/home # grep -r 'guys_name' \/etc\r\nBinary file \/etc\/postfix\/transport.db matches\r\nBinary file \/etc\/postfix\/recipient_bcc.db matches\r\n<\/pre>\n
Because it was in *.db files, I couldn’t fix it by just editing config files in PostFix. <\/p>\n
And because PostFix is not used in the server, I just removed it: <\/p>\n
\r\n# sudo apt-get purge postfix\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
