Not sure if this is a server upgrade issue, Domain or Roundcube setting.
After a recent server upgrade I am now limited to having less than 40 recipients in an email. I don't use this for marketing but to contact our membership only.
Any advice on if this is a roundcube setting that I can change?
Cheers
roundcube does have a setting for it, see 'max_recipients' in your config. it is unlimited by default. it could also be limited by your smtp server.
