I can send emails, using swiftmailer library, to gmail, yahoo ... But I need to send mail via website to @t-com.me. Can someone help me?
Do you own t-com.me?
Telekom ISP might have some anti spam policies.
At what (precise) address do you want to send your emails?
If you need to send @t-com.me then see if they have a similar setup like GoogleMail do in the tutorial above.
Well, thank you for your replies. Problem was with T-Com here in Montenegro as captainjjjacksparrow suggested. Sorry for disturbing. This topic is closed. Thank you so much!
