We migrated SuiteCRM to a new server. SMTP settings were working before but now emails fail silently. No errors in logs. What could be the problem?
I don’t know what I am missing here.
This might help you get more information:
@pgr suggestion is a good one to get specific info, but here are a few things I would check in addtion:
- PHP version is correct
- PHP memory limit it correct
- PHP options required are enabled.
- PHP time limit
- Your server allows outbound SMTP connections (fire wall)
- Your host allows SMTP connections through their relay
- Your SPF records are configured properly to allow new IP of new server
- You have your email routing configured properly in WHM (if you’re using WHM/Cpanel)
- You have transport=dkim_remote_smtp setup if using WHM/Cpanel in tweak settings.
- Your new host may have different SMTP ports.
Those are my top 10.
