Wordpress/Forum Not Sending Email
I installed VestaCP on a VPS (Centos) in June. It has worked perfectly since then. But recently Wordpress and SMF are not sending emails. If you do a password request on Wordpress, it gives no error, and appears to have sent it, but it hasn't. (And I've checked my junk folder)
It worked fine for months, but all of a sudden stopped working. My vps did go down for a few hours somewhat recently, but my host said the reason was they experienced a ddos attack, so I'm not sure if they connect.
Anyway, not sure what to do. Been trying to fiddle around, but I don't know much.
Also, when I try to restart sendmail (not sure if that's the problem or not) I get this message.
Starting sendmail: [ OK ]
Starting sm-client: exim abandoned: unknown, malformed, or incomplete option -L
[FAILED]
Any help on this would be appreciated. Thanks.

Did you setup spf or dkim ?
Have you updated the OS or programs recently?
Any server logs showing anything?
check if you have a parameter -L in
/etc/init.d/mailif you have, try removing it and restart sendmail
Just use external smtp like mandrill.com
Try disabling iptables and fail2ban from VestaCP > Services
Any logs on this ? You should have some logs that may help solving this.. check sendmail server log
telnet mail.google.com 25iptables -X ; iptables -FCheck mail logs
Server restart. Also, using MailJet, MailGun or MandrillApp is a good idea.
